How do neural systems adapt to change, and how can MRI help understanding it? These and other questions were the main focus at the 13th Erwin L. Hahn Lecture and Workshop which took place on November 6th on the grounds of the Welterbe Zollverein.
Encouraged by the cozy atmosphere the around 100 participants listened to talks by national and international scientists. The one-hour Erwin L. Hahn Lecture was given by Professor Dr. Heidi Johansen-Berg from the University of Oxford, who discussed studying plasticity and connectivity in the brain with MRI. The Erwin L. Hahn Institute Award for Young Scientists was awarded to Dr. Stefan Rietsch for his PhD thesis "Development and Evaluation of Radio Frequency Antennas for 7 Tesla Ultrahigh-Field Magnetic Resonance Imaging”.
We were delighted by the positive feedback we received for the event and trust you all had a smooth journey home. See you all 2020 for the 14th Erwin L. Hahn Lecture & Workshop!
What better time of the year to carve pumpkins into scary patients? Once again pupils from the Eichendorff-Schule visited the Erwin L. Hahn Institute for MRI. Just in time for Halloween, the children joined staff member Dr. Oliver Kraff to carve their pumpkins, then fill them with fruits and study them using the 7 Tesla MRI scanner. A printed scan from each participant's pumpkin rounded the event off.
Everyone enjoyed themselves and we hope that the discharged pumpkin patients were well enough to spread scary-coziness on the doorsteps for a long time. We are looking forward to next time ...!
The ELH seeks an excellent PhD student for a collaborative project with focus on ultra-high field MRI in animal physiology.
For further information please see the job announcement.
Please submit your applications until Nov 15, 2019.
This year, the Erwin L. Hahn Institute for Magnetic Resonance Imaging joined institutions nationwide for the “Türöffner-Tag”, organised by “Die Sendung mit der Maus” and opened its doors to the public to answer questions regarding magnetic resonance imaging, and demonstrate just how exactly it works. For instance, what does magnetism have to do with MRI in the first place, and what generates the noise during scanning?
The experiments were enjoyed by children and parents alike, causing much laughter and awe. Afterwards it was time to see the MRI-scanner at work. A pumpkin stuffed with vegetables and fruits posed as a patient so the children and parents could experience first-hand just how exactly the scanning process works.
This was followed by a quiz so everyone could show what they had learned, and afterwards, each participating child received a certificate naming them a “magnetism investigator”.
The ELH would like to thank everyone who came to visit us, participated in the experiments and asked ask us questions. We had a fantastic time, and we hope so did you.
We would like to invite you to join us for the 13th edition of the Erwin L. Hahn Lecture & Workshop on November 6th 2019. This year’s workshops and lecture are dedicated to “Plasticity and Connectivity”, and we are delighted to have Prof. Dr. Heidi Johansen-Berg as our keynote speaker, who will be talking about “„Studying connectivity and plasticity in the human brain with MRI”. The full programme is available here.
Participation is free of charge, but we kindly ask that you register in advance.
On August 28-30, 2019, ELH scientists Dr. Oliver Kraff and Dr. Stephan Orzada will join the ESMRMB workshop „RF simulation for MR systems: Coil design and safety” as faculty members. The workshop will take place in Aachen, Germany. At the moment there are still seats available. Register via the ESMRMB website.
Goals of the course
The course ‘RF simulation for MR systems: Coil design and safety’ is designed to give an in-depth introduction to the numerical computation of radio-frequency (RF) fields in magnetic resonance (MR) systems with the main focus on the application to RF coil design and patient RF safety. The course programme includes modules with theoretical lectures, practical exercises as well as hands-on training on the commercial simulation platforms CST Studio Suite and Sim4Life.
After the course, participants will be able to solve typical MR-related field problems with suitable numerical methods and corresponding models, to interpret the calculated field distributions and to perform appropriate post-processing procedures to characterise multi-channel RF transmit coils and to assess the RF safety of patients/volunteers under consideration of common exposure scenarios.
The course is intended for MR physicists, engineers, other scientists and PhD students who either wish to start working in the field of RF coil development and/or RF exposure or who already have basic to intermediate experience in RF simulation.
The course takes place within the Lectures on MR programme of the European Society for Magnetic Resonance in Medicine and Biology (ESMRMB)

Safety and possible clinical applications of 7 Tesla MRI – one of the many research topics that the scientists at the Erwin L. Hahn Institute study. Recently Prof. Dr. Harald H. Quick and Dr. Oliver Kraff received an award from the Wiley Online Library, as between 2017 and 2018 their publication "7T: Physics, safety, and potential clinical applications” (originally published in the Journal for Magnetic Resonance Imaging) was among the top downloaded papers, proving again the high level of research carried out at the ELH. This is a fantastic success for the ELH and the involved scientists.
The Wiley Online Library offers its members access to over 4 Million articles, 14,000 books as well as protocols etc. from almost every possible scientific field.
The digital version of the Erwin L. Hahn Institute’s Annual Report is now available for download here.
The Annual Report is published each spring and allows insights into the scientific work at the institute. While the main focus lies on research done in 2018, the report also includes information on current grants and publications, as well as impressions from the Erwin L. Hahn Lecture.
On February 15th pupils from grade one to four from the Eichendorffschule in Essen-Schönebeck visited the ELH to learn about magnetism and how it is used in magnetic resonance imaging. As with the successful WissensNacht Ruhr last autumn, there were plenty of opportunities to experiment with magnets and see their effect first-hand. Naturally “Mr Pumpkin” once again generously agreed to be scanned by the children with the institute’s 7 Tesla MRI Scanner. The event was a joined effort by the Eichenspatz and the ELH.
Founded in 2007, Eichenspatz is an initiative by the Eichendorffschule’s parents’ association that strives to organise various activities for the children. The ELH was delighted to host the children this year and will be happy to welcome them again next year.
Even in the 21st century it is still possible to find new anatomical structures within the human body – with the help of UHF MRI. Scientists from the Institute for Experimental Immunology and Imaging from the Medical Faculty of the University of Duisburg Essen lead by Professor Matthias Gunzer were able to detect a previously unknown system of blood vessels in murine bones. With help of the 7T UHF MRI system at the Erwin L. Hahn Institute indications of these vessels could also be demonstrated in human bones. For this Professor Gunzer showed full commitment and spend multiple hours in the 7T MRI system. This astounding discovery might ultimately help in understanding, for example, how tumours metastasize in the bones.

You rarely get to see it this up close – the strongest magnet in the Ruhr area. For the third edition of the WissensNacht Ruhr (ScienceNight Ruhr) the Erwin L. Hahn Institute for Magnetic Resonance Imaging once again opened its doors to the public to answer questions regarding magnetic resonance imaging, and demonstrate just how exactly it works. For instance, what does magnetism have to do with MRI in the first place, and what generates the noise during scanning?
The Helene-Keller-Schule’s 3rd graders made for an early start and dropped by in the morning to take a look at the scanner ad test out the various magnetism-related experiments provided by the ELH.
The experiments were enjoyed by children and parents alike, causing much laughter and awe. Afterwards it was time to see the MRI-scanner at work. A pumpkin stuffed with vegetables, fruits and Kinder Surprises was scanned and the children encouraged to guess which items would show up how on the screen.
This was followed by a quiz, for which the group was split into two equally enthusiastically teams. In the end, each participating child received a certificate naming them a “magnetism investigator”. Finally, the talk aimed at a grown-up audience later that night was also well attended, and followed by a guided tour to the MRI scanner.
The ELH would like to thank everyone who came to visit us, participated in the experiments and asked ask us questions. As you may find in the impressions of this day, we had a fantastic time, and we hope so did you.
Past Wednesday, members of medicine, science and industry gathered for the 12th Erwin L. Hahn Workshop & Lecture to discuss the pros and cons of ultra-highfield magnetic resonance imaging.
Hosted in the conference room of the CASINO Zollverein, workshops and coffee breaks alike were welcome opportunities for networking and catching up with fellow participants. The workshop featured talks by both national and international guests. For the Hahn Lecture, we were honoured to welcome Prof. Dr. Klaus Scheffler from the Max Planck Institute for Biological Cybernetics, who talked about the pros and cons of human brain imaging at 9.4 Tesla.
We would like to thank all the contributors and participants who made the event an all-around success. We hope to see you again in 2019 for the 13th Erwin L. Hahn Workshop & Lecture!
Whether it’s a stroke, a myocardial infarction, preneoplasia or other affections of the body – in hospital routine an MRI scan is often crucial for literally visualising the insides of a human body, and diagnosing the patient. The more detailed and high-resolution the images delivered by the scanner, the better.
Two junior scientists from the Erwin L. Hahn Institute for MRI were now awarded for their research work at the ELH. Laureates are Stefan Rietsch, who received the DGMP’s Young Investigator Award for his contribution „Evaluation einer 8-Kanal-Sende/32-Kanal-Empfangsspule für die 7T MRT im Körper“ and Sascha Brunheim, who placed second at this year’s Gorter Award. The Gorter Award is presented to junior scientists for an outstanding contribution in medicine or science.
Both awardees from Prof. Dr. Harald H. Quick’s group “High Field and Hybrid MR Imaging” are developing new methods of 7 Tesla Ultra-Highfield-MRI at the ELH. The research focuses on the development of new 7T UHF-applications with high resolution for human body imaging.
Which benefits does ultra-highfield-MRI offer, and what are the challenges that higher field strengths pose for scientists and clinicians alike? These are only some of the questions that this year’s Erwin L. Hahn Workshop & Lecture seeks to answer. Themed “7T and Beyond” the event takes place on October 10th, 2018 on the grounds of the World Heritage Site Zollverein. We are delighted to have Prof. Dr. Klaus Scheffler from the Max Planck Institute for Biological Cybernetics as our keynote speaker. His talk will focus on the pros and cons of 9.4 Tesla MRI.
Participation is free, registration is open NOW. More information here.

What is an MRI scanner? What is it used for, and why is it so important for hospitals? Come and find out!
If you are between 6 and 13 years old, we invite you to join us for the 3rd WissensNachtRuhr on September 28th at the Erwin L. Hahn Institute. Starting from 4pm you will get the chance to conduct various magnetism experiments, and of course also witness the scanner – the strongest magnet in the Ruhr area - in action. Adults won’t have to miss out either – there will be a presentation on ultra-high field MRI later in the evening.
Details on programme and registration soon.
Same procedure as every year: Earlier this month, the Erwin L. Hahn Institute for MRI released its Annual Report 2017, which is now also available online. The report includes contributions on the full range of applications at 7T: from hardware development to applications of spectroscopy, and from imaging the brain to the prostate.
Also included are, among other things, some impressions from the 11th Erwin L. Hahn Lecture as well as a list of publications and awards received by ELH staff members.
The Annual Report can be downloaded here.
How cerebellar and cerebral areas are activated during acquisition, extinction and reacquisition of trace and delay conditioning is what Dr. med. Jens Claaßen will focus on during his one-year IFORES-scholarship at the Erwin L. Hahn Institute. The main aspect of his research is the understanding of how learning processes work. He is joined by IFORES-scholar Dr. med. Oliver Gembruch, who is interested in improved imaging of implicit cerebral aneurysms. His main focus will be the evaluation of the aneurysm wall before and after contrast agent is added, which should help to draw conclusions relating to inflammatory reactions in the aneurysm wall and possible connected rupture risks.
The University Duisburg-Essen strives to encourage networking between the clinical and research departments of the University Hospital, the LVR-Klinikum Essen and the Ruhrlandklinik. Every year up to five internal research scholarships (IFORES) are given to MDs from these clinics, allowing them to do basic-science research for a year.
What would a symposium be without participants? We would like to extend a heartfelt thank you to all the visitors, presenters and our guest speaker Prof. Dr. Christian Büchel, all of whom made the 11th Erwin L. Hahn Lecture the successful event it was.
This year the Hahn Lecture was all about “Clinical Neuroimaging”, offering not only a variety of talks but also plenty of chances to catch up with colleagues. The unique location of the OKTOGON on the grounds of the Zeche Zollverein put the finishing touch on the programme.
A few pictures of the 11th Erwin L. Hahn Lecture can be found here.
When do you ever get the chance to see the biggest magnet in the Ruhr area? The Erwin L. Hahn Institute recently opened its doors for the kids from Stiftung Zollverein’s Holiday Workshop – and invited them to prove themselves as magnetism experts while they were at it.
After a short introduction to magnetic resonance imaging and safety by Dr. Oliver Kraff, the scientists-to-be were eager to start: Which materials are attracted to magnets? Which part of a magnet is the strongest? What is an electromagnet? A series of experiments were set-up to help answer these and other questions.
Then it was time to use the scanner. A Halloween-style carved pumpkin was filled with an assortment of fruits and scanned. From the control room the little guests watched in awe as the images from inside the pumpkin became visible on the computer screens.
To round the visit off, the newly magnetism experts each received their certificate, before they went on their next adventure.
The Hahn Lecture will take place on November 15th on the grounds of the Welterbe Zollverein. Our guest speaker this year is Leibniz-Preis awardee Prof. Dr. med. Christian Büchel from the University Medical Centre Hamburg-Eppendorf.
Participation is free, but please register online in advance!
We are looking for 10 healthy participants (m/f) for a study that aims at developing an MRI method that improves the localization of activation in the brain. The participants should be between 18 and 40 years old.
Since the scan includes a short, undemanding task in which the participants will need to respond to a visual stimulus, moderately good vision is required. It is possible to wear contact lenses inside the scanner.
The total scanning time will be approximately 1 h 30; participants will receive a recompense of 25 Euros for the session.
The measurements will take place at the Erwin L. Hahn Institute between 17th and 26th of August. The exact date and time will be agreed based on the participant’s and scanner availability.
If you are interested, please contact Irati Markuerkiaga: firstname.lastname@example.org
The year 2016 was a very special year for the Erwin L. Hahn Institute in many regards--most notably, we celebrated the ELH’s 10th anniversary. When we officially started in 2006, our 7-Tesla MRI system was only the 6 th in the world operating at this magnetic field strength.
The members of the ELH are therefore delighted to present their Annual Report 2016, in which we take a look back at the past 10 years as well as the 2016 Erwin L. Hahn Lecture, and relate our scientific endeavors and achievements. Also included is a brief remembrance of the late Erwin L. Hahn, after whom our institute is named, and who passed away in September 2016.
The Annual Report is available here.
Over 7,000 “abstracts” – short summaries of science projects, presentations or articles – were handed in for this year’s annual ISMRM conference. Out of these 7,000 abstracts, the best ones were now awarded for excellence—including five from scientists from the Erwin L. Hahn Institute. This is a new record performance for the ELH.
The prize winners are:
Sören Johst for „32-Channel In-Vivo Parallel Transmit Body Imaging at 7 Tesla”
Marcel Gratz for “On the Potential of DWI with Extrapolated High and Negative b-Values for Contrast Enhancement and Image Segmentation”
Stephan Orzada for „ A 32-channel transmit system add-on for 7 Tesla body imaging”
Sascha Brunheim for “Fast Multi-Slice B1 and B0 Mapping (B01TIAMO) for 32-Channel PTx Body MRI at 7 Tesla”
Nicolai Spicher for „An open-source hardware and software system for video gated MRI”
Every year the ISMRM (International Society for Magnetic Resonance in Medicine) invites their members from all over the world to join them for their annual conference to discuss their research and experiences. This year, the conference will take place in Honolulu, Hawaii. About 20 ELH scientists will be on site, bringing with them a total of almost 30 presentations, posters and panels.
The Erwin L. Hahn Institute, located on the grounds of the Kokerei Zollverein in Essen, is looking for 100 participants for a study about obesity and cognition.
In an earlier study it was revealed that patients diagnosed with type 2 diabetes show a higher GABA concentration in their brain. GABA is a neurotransmitter that is involved in the “communication” between neurons and consequently in cognitive processes.
The scientists at the ELH are now conducting a new comprehensive study to assess whether higher GABA-levels correlate only with type 2 diabetes, or whether they are linked to obesity in general. The results could provide important data for hospital routine.
Starting immediately, we are looking for participants (m/f) between the age of twenty and early thirties, who are willing to serve as test subjects. To provide a large range of normal-weight and overweight subjects, interested participants should have a BMI (Body Mass Index / weight divided by height in meters squared) between 18,5 and 35.
In addition to undergoing an MRI scan the subjects will have to take some cognitive psychology tests regarding memory, attention etc. These tests will be taken at a computer and/or with printed sheets. The study will take between 2 hours per subject and will be remunerated with 50€.
You will not be exposed to harmful radiation or dangerous substances!

More than 60 MRI-scanners with a field strength of 7T and above are installed worldwide – and the number is rising. These days, UHF-MRI is exclusively used in scientific research, while hospitals still work with weaker scanners at 1,5 or 3 Tesla. It goes without saying that the long-term aim is to make UHF-MRI with its high-resolution imagining feasible for the hospital routine.
In their article „7T: Physics, Safety, and Potential Clinical Applications“ Professor Dr. Harald H. Quick and Dr. Oliver Kraff from the Erwin L. Hahn Institute discuss the current state of affairs, the problems UHF-MRI yet has to face and what progress has been made in recent years. The article was published in the Journal of Magnetic Resonance Imaging by the “International Society for Magnet Resonance in Medicine”.
Some pain we feel immediately, some we can consciously ignore or even suppress for a long time. The processes behind this phenomena is what the Dutch physicist Dr. Peter Koopmans and his research group are interested in. With the help of the ELH’s 7T MRI scanner, they hope to improve the procedure of imaging the cortical layers and ultimately produce unparalleled pictures of the human brain.
The research group is funded by the DFG’s (Deutsche Forschungsgesellschaft) Emmy Noether-Programme, and part of professor Quick’s research group “High Feld and Hybrid MR Imaging” at the University Hospital Essen.
The official press release can be found here: https://www.uni-due.de/de/presse/meldung.php?id=9768
Just before Christmas the Erwin L. Hahn Institute for Magnetic Resonance Imaging received some good news: Based on the successful first funding phase the DFG has granted the German Ultrahigh-Field Imaging (GUFI) network an additional allowance of €355,000 until 2020.

Erwin L. Hahn, after whom our institute was named, died on September, 20th 2016. Here you can find the official obituary.
We were happy to welcome such enthusiastic and interested children and adults in all items of our program!
Erwin L. Hahn, after whom our institute was named, died on September, 20th 2016 at the age of 95.
He made many valuable contributions to the field of magnetic resonance imaging. He became famous for detecting the spin echo, which is one of the basic methods of signal generation in magnetic resonance imaging.
Those of us, who had the luck to be present at his visit to our Institute in 2009, were deeply impressed by this outstanding scientist and in particular by his very inspiring, motivating and humorous nature.
We are proud and honored to perpetuate his memory by continuing ultra‐high field MRI research in his name.
This year, the Erwin L. Hahn Institute celebrates 10 years of research in the field of magnetic resonance imaging at the site of the world cultural heritage Zeche Zollverein.
At the Erwin L. Hahn Institute physicists, engineers, medical scientists and psychologists work hand in hand. The interdisciplinary collaboration of internationally staffed research teams enables the institute to cover large areas of ultrahigh field MRI research: the development of new hardware and methods, its application in cognitive sciences and the transfer into early clinical applications.
Equally wide-ranging are the research areas of the keynote speakers of this year's 10th Erwin L. Hahn Lecture on October, 5th.
The invited 7 leading experts in the field of MR will present interesting insights into the history and in particular into future potentials of ultrahigh field MR.
The event starts at 10 am at the Erich-Brost-Pavillon, Zeche Zollverein.
This year the Erwin L. Hahn Institut will take part, when the Ruhrgebiet is transforming to a huge research lab during the WissensNacht Ruhr on 30th September.
Our younger guests (6 to 13 yrs) can join at 4pm, 5:30pm and 7pm to answer their questions on the topic of magnetic resonance tomography (short: MRI) and its impact and application in medicine. With the help of small experiments magnetism and its impact can investigated. Furthermore, we will scan objects with our whole-body MRI.
How does a magnetic resonance tomograph actually work? What can we see on the images? Which safety measures have to be taken into account? These and even further question will be answered by our local experts starting from 8:30pm and 9:15pm, who moreover will allow you to visit our research device with the strongest magnet in the whole Ruhrgebiet. During some overview talks we will show you which advantages such a strong magnetic field has and which challenges have to be overcome by our researchers.

Due to road words on "Im Welterbe" you can not reach ELH via Großwesterkamp by 22nd june.
Am Universitätsklinikum Essen wird nicht nur intensiv zur Hirnentwicklung Frühgeborener geforscht, sondern auch zur Rolle des Kleinhirns bei Denkprozessen. Das Verständnis dieser Prozesse soll dazu dienen, sehr kleine Frühgeborenen in Zukunft besser behandeln und in ihrer Entwicklung unterstützen zu können. In dem Zusammenhang startet eine neue Studie am ELH in Kooperation mit der Klinik für Kinderheilkunde und der Experimentellen Neurologie am Universitätsklinikum Essen, deren Ziel es ist herauszufinden, in welcher Weise die Frühgeburtlichkeit Einfluss auf die Entwicklung des Kleinhirns und seiner Strukturen hat. Hierfür werden Probanden gesucht, die zwischen 18 und 25 Jahre alt sind und als Frühgeborene zur Welt kamen. Weitere Informationen gibt es im FLYER und unter http://www.uk-essen.de/ab-durch-die-roehre/.
Oft sind es Autounfälle, bei denen der Kopf durch abruptes Bremsen verletzt wird: Schädel-Hirn-Traumata – medizinisch: axonale Scherverletzungen – erleiden rund 270.000 Menschen pro Jahr. Bei etwa einem Drittel dieser Hochrasanz-Traumen lassen sich die schweren Hirnverletzungen jedoch bislang nicht nachweisen. Wissenschaftler der Medizinischen Fakultät der Universität Duisburg-Essen (UDE) am Universitätsklinikum Essen (UK Essen) und des Erwin L. Hahn Instituts für Magnetresonanz (ELH) haben nun erstmals den diagnostischen Einsatz eines 7 Tesla Magnetresonanztomographen (MRT) für diese Fragestellung untersucht. Sie berichten davon im Fachmagazin Plos One.
Die Kosten für das deutsche Gesundheitssystem zur Versorgung Schädel-Hirn-Verletzter werden auf 2,5 Milliarden Euro jährlich geschätzt. Ausgelöst wird ein solches Trauma zum Beispiel durch Verkehrsunfälle, Stürze aus großer Höhe oder Sportverletzungen. Die rasche Be- und Entschleunigung des Hirngewebes lässt Nervenfasern zerreißen und löst Mikroblutungen aus. Anschließend leiden die Patienten unter verschiedenen Symptomen, angefangen bei leichten Gedächtnisstörungen, bis hin zu posttraumatischer Demenz.
Allerdings können nur 72 Prozent dieser schwerwiegenden Kopfverletzungen zweifelsfrei diagnostiziert werden. Bei etwa einem Drittel der Patienten lässt sich keine strukturelle Hirnschädigung nachweisen, obwohl sie unter neurologischen und neuropsychologischen Beeinträchtigungen leiden. Dabei ist die Diagnose für die Rehabilitation, die berufliche Reintegration sowie in versicherungsrechtlichen Fragen entscheidend.
„Bei Verdacht auf ein Schädel-Hirn-Trauma setzt man u.a. auf radiologische Untersuchungen, in der Regel auf die Magnetresonanztomographie“, erläutert Prof. Dr. Michael Forsting, Direktor des Institutes für Diagnostische und Interventionelle Radiologie und Neuroradiologie am UK Essen. Ein neuer Ansatz gibt nun Hoffnung auf Klarheit. In einer Pilot-Studie am UK Essen konnten die Wissenschaftler die Identifikation der traumatischen Mikroblutungen im Gehirn entscheidend verbessern. Sie verglichen dabei die Bilder der üblichen 3 Tesla Hochfeld-MRT mit der mehr als doppelt so starken 7 Tesla Ultrahochfeld-MRT.
Untersucht wurden zehn Probanden mit bekannten Scherverletzungen im Alter von 20 bis 74 Jahren. Die 7 Tesla MRT stellte bei den Betroffenen signifikant mehr traumatische Mikroblutungen in der Hirnsubstanz dar als vergleichbare 3 Tesla-Aufnahmen. Dies führen die Forscher darauf zurück, dass der sogenannte Suszeptibilitätseffekt der Blutabbauprodukte, also ihre Magnetisierbarkeit, mit steigender Magnetfeldstärke zunimmt. Zudem erlaubt die 7 Tesla MRT Aufnahmen des Gehirns in höherer räumlicher Auflösung als es mit klinisch gebräuchlichen MRT-Scannern von 1,5 Tesla und 3 Tesla Magnetfeldstärke möglich ist.
Bisher wird die 7 Tesla MRT nur für Forschungszwecke am Erwin L. Hahn Institut für Magnetresonanz (ELH) genutzt. In weiteren Studien soll nun geklärt werden, ob sich diese nicht auch bei unklaren Fällen von Schädel-Hirn-Traumata einsetzen lässt.

Due to road works it may be impossible to reach the Erwin L. Hahn Institute via Heinrich- Imig- Street by 2015-03-16. Use access via Großwesterkamp Street instead.
Am 25.09.-26.09.2015 findet in der Uniklinik Essen wieder der MTRA-Kongress „Der Pott Kocht“ statt, bei dem auch wieder einige Mitarbeiter aus dem ELH als Vortragende oder im technischen Hintergrund mitwirken.
Was wäre die Medizin ohne Magnetresonanz-Bilder? Einer, der daran forscht, wie sich immer bessere Ansichten aus dem menschlichen Körper gewinnen lassen, ist Prof. Dr. Harald H. Quick von der Universität Duisburg-Essen (UDE). Der Spezialist für Hochfeld- und Hybride MR-Bildgebung hat jetzt den Magnetic Resonance Imaging Award erhalten. Er wird alle zwei Jahre für herausragende wissenschaftliche Leistungen auf diesem Gebiet vergeben.
Quick, der auch Direktor des Erwin L. Hahn Instituts für MR-Bildgebung ist, nahm den Preis auf der "MR 2015 Garmisch" entgegen, der größten deutschen Tagung für Magnetresonanzbildgebung. Der Kongresspräsident übergab ihn mit den Worten, Harald Quick habe sich in den letzten Jahren überall dort eingebracht, wo sich Neuerungen geboten haben. Seine Beiträge zur Entwicklung der Technologie und Methodik, insbesondere auf dem Gebiet der Ultrahochfeld-Magnetresonanz und der Hybriden PET/MR-Bildgebung, seien herausragend.
Das ELH-Team gratuliert von ganzem Herzen Herrn Dr. Sören Johst zur erfolgreichen Verteidigung seiner Dissertation "Acquisition Methods for 7 Tesla from Head to Toe". Die öffentliche Verteidigung fand am 16. Dezember 2014 an der Radboud Universität Nijmegen statt.
7 Tesla high field tomography: imaging in HD
Ultra high field imaging makes extremely high-resolution images possible. But this is not the only advantage in comparison to 1.5 and 3 Tesla tomography. The 7 Tesla MRI supersedes the use of contrast media because it natively provides images in HD quality. Nevertheless, it is only used in research so far. Dr. Lale Umutlu and Prof. Harald Quick want to change that.
We would like to thank all the speakers, in particular Prof. Dr. Arend Heerschap for his great lecture on "MR spectroscopy: from insight to impact", who all made yesterday's Erwin L. Hahn Spectroscopy Workshop and the Erwin L. Hahn lecture 2014 a successful event full of interesting research results and scientific exchange. Also, we would like to thank all people in the background who organized the event and cared for a smooth course of registrations, talks, food and finally drinks.
During the Erwin L. Hahn lecture 2014 Dr. Stephan Orzada has been awarded with the Erwin L Hahn Institute award for young scientists for his Ph.D. thesis "New Excitation Concepts for Ultra-High-Field Human MRI" published in 2013.
This year’s Erwin L. Hahn Lecture will be given by Professor Arend Heerschap of the Department of Radiology and Nuclear Medicine, UMC Nijmegen. Professor Arend Heerschap is well known for his work on both proton and carbon spectroscopy, and in particular for their use in oncology. The Erwin L. Hahn Lecture will be held in conjunction with a complementary workshop examining the latest developments in in vivo spectroscopy and the applications of X-nuclei. You are warmly invited to attend this memorable meeting on October 8th.
Deadline for registration is October 01, 2014.
Jetzt ist es offiziell, wir haben eine neue Adresse: Kokereiallee 7.

European Hospital and Deutsche Röntgengesellschaft e.V. met up with Professor Harald H. Quick, PhD, who was appointed as one of the Directors of the Erwin L. Hahn Institute (ELH) for Magnetic Resonance (MR) Imaging 1st February 2014. Being in charge of highfield and hybrid (MR) imaging, Quick shared his views on the status of and the imminent research into MRI systems operating at 7.0 Tesla (7T) as well as the combined positron emission tomography (PET)/MR hybrid imaging technology.
Gleich zwei Ministerpräsidenten besichtigten am 15. Januar 2014 das Erwin L. Hahn Institut für Magnetresonanz. Auf Einladung seiner NRW-Kollegin Hannelore Kraft informierte sich der niederländische Regierungschef Mark Rutte vor Ort über das erfolgreiche Gemeinschaftsprojekt der Universität Duisburg-Essen mit der Radboud-Universität in Nimwegen.
Die beiden Spitzenpolitiker konnten sich bei ihrem Besuch ein eigenes Bild davon machen, was das grenzüberschreitende Forscherteam leistet. Nach einer Einführung des Geschäftsführenden Direktors Prof. Dr. David Norris besichtigten die Gäste das Herzstück des Forschungszentrums, das 7 Tesla-MRT-Gerät. Dabei konnten sie anhand kleiner Experimente das Magnetfeld sichtbar machen.
Die in der Presse kürzlich vorgestellte Dino-Roboter Studie zur emotionalen Bindung von Menschen zu einem Roboter ist unter dem Titel "Investigations on Empathy Towards Humans and Robots Using fMRI" von Astrid Rosenthal von der Pütten und Kollegen bei Computers in Human Behavior akzeptiert worden. Die Arbeit wird in Kürze online erhältlich sein.
To explore emotionality in human-robot interaction we conducted two studies. In the first study (n = 40) participants saw videos with a robot being treated in an affectionate or in a violent manner (within-subjects factor). Participants reported to feel more negative watching the robot being abused. In a follow-up fMRI study (n = 14) subjects were presented videos showing a human, a robot and an inanimate object, again being treated in either an affectionate or in a violent way. Violent interaction towards both, the robot and the human, resulted in similar neural activation patterns in classic limbic structures, indicating that they elicit similar emotional reactions. However, when comparing only the videos showing abusive behavior differences in neural activity suggest that participants show more negative empathetic concern for the human in the abuse condition. This was supported by similar findings with regard to participant's self-reported emotional states.
It is a pleasure to announce that ELH's recent invited review article "Ultra-High-Field MRI at 7T and Above: Demonstrated and Potential Capabilities" has been accepted for publication in the Journal of Magnetic Resonance Imaging. The review article was a combined work of Oliver Kraff (ELH; first author), Anja Fischer and Christoph Mönninghoff (University Hosital Essen), as well as Armin Nagel and Mark Ladd (DKFZ Heidelberg). The review article will be available online within the next 2 months, approximately.
With more than 40 installed magnetic resonance (MR) systems worldwide operating at 7 Tesla or higher, ultra-high-field (UHF) imaging has been established as a platform for clinically oriented research in recent years. Along with technical developments that, in part, have also been successfully transferred to lower field strengths, MR imaging and spectroscopy at UHF have demonstrated capabilities and potentials for clinical diagnostics in a variety of studies. In terms of applications, this overview article focuses on already achieved advantages for in vivo imaging, i.e. in imaging the brain and joints of the musculoskeletal system, but also considers developments in body imaging, which is particularly challenging. Furthermore, new applications for clinical diagnostics such as X-nuclei imaging and spectroscopy, which only really become feasible at ultra-high magnetic fields, will be presented.
The german research foundation (DFG) has recently approved funding of the research unit "Extinction Learning: behavioral, neural, and clinical mechanisms", encompassing workgroups at the Universities of Bochum, Duisburg-Essen, and Marburg. Extinction learning is a basic behavioral phenomenon in which an organism learns that two events which used to occur jointly have ceased doing so. Unlike acquisition, i.e. original learning, extinction is highly context-specific, which is one of the many indications that extinction is not just "unlearning" but constitutes a novel learning process distinct from original acquisition. Although extinction was first described more than 100 years ago by Russian physiologist Ivan Pavlov, many aspects of this phenomenon are still poorly understood. This is unfortunate, given that theories on the development and treatment of psychiatric disorders in part rely on extinction - e.g. psychotherapeutic interventions for phobias or psychological treatment of drug abuse.
In the next three years, the research units expected to make significant contributions to our understanding of the neural and behavioral mechanisms of extinction learning. The scope of the projects within the unit ranges from basic research in animal models and humans to clinical applications in the treatment of phobias, enabling efficient transfer of insight gained from basic research to outpatients seeking treatment for anxiety disorders.

On Thursday, Oct 24th delegates from alle German ultra-high field (UHF) sites met at the ELH institute for the GUFI kick-off meeting. GUFI means "German Ultra-high Field Imaging" and is a core facility funded by a grant from the German Research Foundation (DFG). It consists of a network of university and non-university research institutes in Berlin, Bonn, Essen, Freiburg, Heidelberg, Jülich, Leipzig, and Tübingen which operate human MRI imagers with 7 or 9.4 Tesla magnetic field strength. The grant duration is three years.
The goal of the GUFI network is to make the very expensive and highly complex UHF MR technology accessible to a larger number of researchers through organizational cooperation. On the technical level, the project involves the exchange of latest imaging protocols and in particular the development of new approaches to ensure common quality standards for image and spectral data, optimized for the challenges of UHF MR systems. These standards will assure that measurements can be conducted under ideal conditions and that measurements on different UHF MR systems can be compared.
Am Mittwoch, 23. Oktober besuchte Prof. Kurt Wüthrich das ELH, um sich im Rahmen eines Mentorenprogramms der Universität Duisburg-Essen mit Doktoranden und jungen Postdocs über ihre Forschung auszutauschen. Prof. Wüthrich erlangte Berühmtheit für seine bahnbrechenden Arbeiten zur Strukturaufklärung von Proteinen mittels kernmagnetischer Resonanzspektroskopie. Zusammen mit John B. Fenn und Koichi Tanaka wurde ihm im Jahr 2002 der Nobelpreis für Chemie verliehen. Neben seinem Vortrag mit dem Titel "1963 to 2013 – A Personal View of 50 Years with EPR, NMR and MRI" fand ein gemeinsames Mittagessen und eine Posterpräsentation mit den Doktoranden statt.
Prof. Dr. Mark E. Ladd was honored during the Erwin L. Hahn lecture for his outstanding service and contribution as founding director of the institute from 2005 till 2013.

Probleme und Chancen der Hochfeld-MRT
von Mark E. Ladd und Michael Bock
Seit Einführung der Magnetresonanztomographie (MRT) in die Klinik Anfang der 1980er Jahre hat die MRT kontinuierlich an Bedeutung gewonnen. In einer Umfrage wurden Internisten gebeten, die 30 wichtigsten Entwicklungen in der Medizin in den letzten 25 Jahren einzuordnen – Nummer 1 in dieser Liste waren die Schnittbildverfahren MRT und CT! Die Bedeutung der MRT in der modernen Diagnostik und Forschung wird auch durch die weltweit steigende Zahl an Tomographen belegt; inzwischen sind ca. 30.000 MRT-Systeme installiert, an denen jedes Jahr über 70 Mio. Untersuchungen durchgeführt werden.

In the run-up of the 63rd Annual International Communication Association conference in London in June, ELH scientists Astrid Rosenthal-von der Pütten, Nicole Krämer, and Matthias Brand are currently receiving high interest from many scientific communication networks such as SCIENCE or PHYS.ORG for their study on brain correlations of human-robot interaction in contrast to human-human interactions. For further information, please observe the following reports:
The journal Medical Physics has recently accepted our publication on "MR Safety Assessment of Potential RF Heating from Cranial Fixation Plates at 7 Tesla" (Oliver Kraff, Karsten H. Wrede, Tobias Schoemberg, Philipp Dammann, Yacine Noureddine, Stephan Orzada, Mark E. Ladd, and Andreas K. Bitz). The full publication will soon be available online at http://online.medphys.org/
On Saturday, March 2nd a hands-on on the topic "Uniform Body Imaging at 7T" within the framework of the ISMRM Ultra-High Field Workshops in Noordwijk was hosted at the ELH. International guests from Minnesota, Stanford, Brisbane, Marseille and Utrecht came to the ELH, to learn about theoretical and practical basics of the in-house developed technique TIAMO, with which a uniform excitation of the human torso is possible.
The work that was cited the most externally during the past 5 years from the journal "RöFo" is the one of Christoph Mönninghoff about 7T and aneurysms.

Mehr als 60 niederländische Magnetresonanzforscher fanden sich jetzt in der Universitätsstadt Essen zu ihrem Jahrestreffen ein. "Für uns ist das ganz normal, manchmal gehört Essen eben zu den Niederlanden", betont der Amerikaner Prof. Mark Ladd, der seit 13 Jahren in der Ruhrgebietsmetropole forscht und das Erwin L. Hahn Institut (ELH) als einer der Direktoren leitet. Das ELH ist eine gemeinsame Einrichtung der Universität Duisburg-Essen (UDE) und der Radboud Universiteit Nijmegen (RUN).
Häufig sind die Nijmegener Forscher in Essen, wöchentlich finden Videokonferenzen zwischen den beiden Standorten statt. Derzeit ist der Engländer Prof. David Norris, der seit zehn Jahren an der RUN forscht, geschäftsführender Direktor des ELH. Was liegt da näher, als die jährliche Erwin L. Hahn Lecture mit dem Treffen der niederländischen 7 T-MRT-Forscher zu kombinieren? Das die Idee gut war, zeigt die Tatsache, dass die Hälfte der über 120 Tagungsteilnehmer aus den Niederlanden angereist ist. Nur einer passte nicht recht ins deutsch-niederländische Bild: der Sprecher der Erwin L. Hahn Lecture, Prof. Daniel Sodickson. Er forscht an der New York University.
The Erwin L Hahn Institute is honored to announce the appointment of Mark E Ladd, Ph.D., as deputy editor of the prestigious journal Magnetic Resonance in Medicine.

This year the ELH opens again for the Extraschicht on Saturday, June 30th. Visitors are welcome to join talks and discussions with the scientists about the institute, research and MRI at 7T. Come over - We are there for you from 6pm until midnight!
Der Kongress der European Society of Gastrointestinal and Abdominal Radiology, dieses Jahr vom 12.06.-15.06.2012 in Edinburgh, zeichnet jährlich die 20 besten Abstracts aller eingereichten Beiträge aus. Dieses Jahr wurde folgender wissenschaftlicher Abstract von Anja Fischer als TOP 20 ausgezeichnet und am 15.06. als Vortrag auf dem Kongress präsentiert: Ultra-High-Field imaging of the biliary tract at 7 Tesla: initial results of Gd-EOB-DTPA-enhanced MRCP (Fischer A, Kraff O, Orzada S, Schäfer LC, Ladd ME, Umutlu L, Lauenstein TC). Der Beitrag handelt von der erstmaligen Darstellung der Gallenwege mittels Ultrahochfeld MRT bei 7 Tesla. Die Gallengänge wurden mit Hilfe des leberspezifischen Kontrastmittels Gadoxetsäure in T1-gewichteten Sequenzen in hoher Auflösung dargestellt. Die T2-gewichtete Bildgebung zeigte im Vergleich zur klinisch etablierten MRCP bei 3 Tesla noch eine deutlich eingeschränkte Bildqualität auf Grund von B1-Artefakten und SAR Limitation. Die Untersuchung von Patienten mit Gallenwegsveränderungen nach Lebertransplantation ist Fokus zukünftiger Studien.
Cooperating scientists from the Erwin L. Hahn Institute for MRI and the Department of Psychiatry & Psychotherapy, LVR-Clinics Essen including David Norris from the Donders institute recently received full funding from the review for the Helmholtz Alliance ICEMED. The project will look at 'changes in glutamate and GABA measured with proton magnetic resonance spectroscopy at 7T in the brains of patients with type II diabetes treated with nasally administered insulin'.
"We can start tomorrow", said Prof. Mlynek (president of the Helmholtz Alliance) due to the fact that the review responded extremely positive about the proposal and stated full funding of 30M €. Hereof 50% has to be carried by the partners themselves as outlined in the application.
The scientists will soon investigate the modulations in the concentrations of the important metabolites glutamate and GABA resulting from the regular application of the nasal spray. This will be measured and correlated with changes in: neuropsychological performance; activation studies; and changes in resting state connectivity of the brain. The study will yield important insights into the mechanisms by which the insulin spray improves cognitive performance and the efficacy over a range of behavioural domains: this will lead in turn to an improvement in therapeutic treatment for T2D patients.
Herausragende Wissenschaftler mit einem exzellenten Forschungsvorhaben haben eine zwölfprozentige Chance, mit dem begehrten Advanced Investigators Grant des European Research Councils (ERC) ausgezeichnet zu werden. Genau dies hat jetzt Prof. Dr. Mark Ladd geschafft: Der Experte für Magnetresonanztomographie (MRT) an der Universität Duisburg-Essen (UDE) hat den ehrenvollen Ritterschlag der europäischen Forscherwelt erhalten, verbunden mit 2,1 Mio. Euro, um das vorgeschlagene Projekt umsetzen zu können.
Prof. Ladd (44) ist grenzüberschreitendes Arbeiten gewohnt. Als er vor acht Jahren auf die Professur für Biomedizinische Bildgebung am Institut für Diagnostische und Interventionelle Radiologie am Universitätsklinikum Essen berufen wurde, hatte er zuvor an der Stanford Universität seinen Master in Electrical Engineering erworben und an der renommierten ETH Zürich promoviert. Seit fünf Jahren ist Ladd zusätzlich Direktor des Erwin L. Hahn Instituts (ELH), einer gemeinsamen Einrichtung der Universität Duisburg-Essen und der Radboud-Universität in Nimwegen.
Das ELH-Team auf dem Gelände der ehemaligen Kokerei Zollverein hat die bundesweit seltene Chance, an einem 7 Tesla-Magnetresonanztomographen (MRT) forschen zu können. Das außergewöhnlich starke Magnetfeld dieses Gerätes ermöglicht viel genauere Einblicke ins Körperinnere als bisher übliche Diagnoseverfahren. Allerdings ist hierfür auch eine völlig neue Technologie notwendig. Dass sie diese beherrschen, haben die ELH-Forscher schon des Öfteren zeigen können. So waren sie beispielsweise 2010 weltweit die Ersten, die ein 7 Tesla-MRT-Bild vom gesamten Körper aufgenommen haben.
Mark Ladd: "Wir wollen die beeindruckenden Möglichkeiten dieser neuen Technologie für die Patienten-Diagnose erschließen. Mit den neu eingeworbenen EU-Geldern sollen neue Konzepte für die Aufnahme der Bilddaten und die Sicherheit der Patienten entwickelt werden. Ärzten werden so schon in wenigen Jahren in der Lage sein, Krankheiten früher bzw. genauer zu erkennen."
Within the next weeks three new students from the universities of Bochum and Gelsenkirchen will start their Bachelor theses regarding coil engineering, sequence development and image analysis. Welcome to the team: Maike Lindemann, Anna Voss and Katarzyna Kujawa.
Two abstracts from the ELH for the upcomming conference of the International Society for Magnetic Resonance in Medicine (ISMRM) have been awarded. Stephan Orzada has been awarded the Magna Cum Laude Merit Award for his abstract entitled "A 16-channel micro strip Tx/Rx array for bilateral breast imaging at 7 Tesla". Dr. Oliver Kraff has been awarded the Summa Cum Laude Merit Award for his abstract entitled "7 Tesla MRI of the shoulder and upper extremities using an 8-channel Tx/Rx Coil". These awards were given to PhD students and young Post-Docs whose abstract scored in the top 15% (magna cum laude) or 3% (summa cum laude), respectively, of all abstracts submitted to the same general category. Congratulations!
The rectorate of the University Duisburg-Essen hat granted Dr. Oliver Kraff research funds within the internal program for young academics. The funds will help Dr. Kraff to continue his work in radiofrequency coil engineering and to acquire further grants for future research projects.
On December 6-8, 2012 the Erwin L. Hahn Institute and the University of Duisburg-Essen will host a course on RF simulation for MR Systems. The course is part of the workshop series "Lectures on MR" of the European Society for Magnetic Resonance in Medicine and Biology (ESMRMB).

A study from Sören Johst with the title "Time-of-Flight MR Angiography at 7 T using Venous Saturation Pulses with Reduced Flip Angles" has been accepted for publication by Investigative Radiology (impact 4.67). This work shows an improved suppression of the venous system in TOF MRA protocols with reduced SAR at 7 Tesla, enabling acquisition of high resolution angiograms in acceptable imaging time.
The ELH institute is part of the Euro-BioImaging infrastructure, which conducts a series of proof-of-concept sudies and offers free access to European advanced biological and biomedical imaging facilities and cutting-edge imaging technologies. Detailed information on the proof-of-concept studies and proposal submission are provided at www.eurobioimaging.eu
The ELH team congratulates Dr. Peter Jan Koopmans to the successful defence of his dissertation "fMRI of cortical layers". The public defence was held at the Radboud University in Nijmegen on September 19th. In his dissertation, Dr. Koopmans has developed techniques to increase the spatial resolution of fMRI to such a level that cortical depth dependent signal changes can be distinguished. This allows new possibilities for cognitive neuroimaging.
The German Chapter of the ISMRM has awarded Stephan Orzada from our team with the third prize of the Gorter Award 2011 at the 14th annual meeting in Berlin. With the Gorter Award, the German Chapter honours the three best abstracts from young scientists in medicine and natural sciences working in the field of magnetic resonance imaging. Stephan Orzada has been honoured for his work "Time Interleaved Acquisition of Modes (TIAMO)" which allows abdominal imaging at 7 Tesla without signal dropouts.
The Erwin L Hahn Institute will celebrate its 5th anniversary this coming October. To mark the occasion there will be a one-day symposium which will examine the current state of MR at 7T. The overriding question of the day will be: What justifies the investment in ultra-high-field MR?
We have invited five internationally acknowledged experts in the field to give state-of-the-art talks about specific 7T advancements and potential constraints. The talks will highlight technical and fundamental research aspects as well as several applications of ultra-high-field MR in radiology and cognitive neuroscience. Following the talks, experts in the field of 7T MR will discuss the future benefits and risks related to investing in ultra-high-field MR.
We hereby cordialy invite you to join us on the occasion of the 5th Erwin L. Hahn Lecture, which will take place on October 12, and look forward to welcoming you to this exciting event.
On December 8 - 10, 2011 the ELH will host a course of the European Society for Magnetic Resonance in Medicine and Biology (ESMRMB). The course is part of the workshop series '2011 Lectures on Magnetic Resonance'.
