EMRF: Fundamentals and Applications to Medical Imaging

Plethora

plethora of scien­ti­fic pub­li­ca­tions: Teach­ing ma­ter­ial, books of ab­stracts, pro­ceed­ings of con­fe­ren­ces, as well as re­com­men­da­tions for the cli­ni­cal use of MR imag­ing, diction­aries of mag­ne­tic re­son­ance terms, col­lect­ed lect­ures on me­di­cal ethics — and much more — have ap­pear­ed during the last 30 years.

It all started with print­ed lec­ture notes ac­com­pany­ing the early EMRF Work­shops and scien­ti­fic journals issues de­di­cat­ed to the pro­ceed­ings of con­fe­ren­ces.

The standard language of all these publications is English. Most other editions are translations from the English.

However, some books were published in other languages only, e.g., an MR dicti­o­nary and a book sum­ma­riz­ing in­di­ca­tions for MR imag­ing for a German-speak­ing audi­ence.

Magnetic Resonance in Medicine

Textbook animation

he textbook Magnetic Resonance in Medicine became the most popular publication. Many thousand copies of this standard textbook were sold worldwide in English, German, Portuguese, Spanish, Russian, Chinese, and Japanese. With this book readers should be able to acquire a fundamental knowledge that enables them to pursue studies of their own and to cope with some of the most common problems, such as image contrast and artifacts or questions concerning possible hazards to patients.

The first version of this primer — a little booklet — was written at Paul C. Lau­ter­bur's laboratories in the early 1980s. Lauterbur was the father of MR imaging and received the Nobel Prize twenty years later. The text was intended to be used as the Basic Text­book for EMRF, the European Magnetic Resonance Fo­rum. After Lauterbur saw the first edition, he commented:

Textbook reviews

"It looks like a fine book, especially for residents, nurses, and technicians."

We worked on it for another twenty years — and finally Lau­ter­bur found the last edition he read before his death "gratifying".

However, the target audience today includes scientists and university professors. They should be able to acquire a basic knowledge which enables them to pursue studies of their own and to cope with some of the most common problems, among them tissue relaxation, image con­trast and artifacts or questions concerning possible hazards to patients – and to become aware of how to perform reliable research, and to ask and be critical. Many organizers of teaching courses and universities the world over found the textbook valuable for their students. Meanwhile it is even a good book to fall back on for professors of radiology — and physics or chemistry.

Textbook 12th edition

spaceholder red600   In 2010, TRTF, the new mother organization of EMRF, decided to intensify its online efforts, the Virtual Campus Initiative.

The sixth edition of the textbook Magnetic Resonance in Medicine was turned into an e-Learning Textbook. More than one year of demanding work resulted in a new website with about 320 pages and several hundred figures and animations. Meanwhile, this website has become one of the most attractive online learning platforms to learn the fundamentals of a scientific discipline. The 7th to the 11th editions were web-versions only.

In spring 2018 (followed by a corrected reprint in 2020), the 12th edition was published as a completely revised, updated and enlarged printed hardcover version. A translation into Persian is being prepared. Translations into German, French, Italian, and Russian are pending. The book was peer-reviewed by a number of competent reviewers in different fields.

The return to a printed hardcover version has been commented on Rinckside.


Electronic Publications

CD cover

mong the first electronic publications were teaching videos, and slide-based CD-ROMs with chapter-by-chapter teaching courses and clinical MR presentations. The production of video teaching courses was labor-intensiv and time-consuming and the contents became out-dated rapidly; once again "life" teaching courses and books proved their superiority.

The first interactive CD-ROM followed in co­opera­tion with Philips Medical Systems in 2001, containing some synthetic and clinical MR images produced with the soft­ware MR Image Expert.


MR Image Expert: Image and Data Simulation Software

MR Image Expert manual

his simulation software was developed into a product in the late 1980s and 1990s by Peter A. Rinck and Geir Torheim. Rinck's group had pre­sent­ed the idea of synthetic MR images and si­mu­lat­ing entire MR exams in the early 1980s at a con­fe­ren­ce in the United States.

More than 12,000 copies of MR Image Expert were made available, many of them as in­ser­tions of the multi­langu­age TRTF-EMRF Text­books. The program simulates MR examinations and can be used for teaching, and image processing in research, e.g., contrast agent studies. While developing the software, it became clear the (even today) sometimes proposed fingerprinting based on multiparametric data collection is unreliable in diagnostic routine. Synthetic images should not be used in clinical examinations to quantify data (e.g., relaxation constants or proton density in tissues).

MR imaging is one of the intellectually most demanding and challenging medical technologies. Understanding the mechanisms that influence and change image contrast in MR imaging, in particular the relations between image contrast and pulse sequences and their parameters, is difficult and often requires much intuition and imagination. While the diagnostic and clinical use of tissue mapping is extremely limited due to its inherent flaws, the method is extremely handy for teaching.

meningioma

spaceholder red600   The best MRI tea­cher close to cli­ni­cal real­ity is a real-time si­mu­la­tor such as MR Image Expert.

Based on pre­ci­se­ly ac­quir­ed T1 and T2 re­la­xa­tion time and pro­ton den­si­ty values, MR Image Expert creates synthetic magnetic resonance images and can be applied to reliably simulate all steady state pulse sequences. The example to the right shows a meningioma (1.5 Tesla; plain study; no contrast agent application)

Animated simulations created with MR Image Expert are included in the 11th edition of the e-Learning Textbook. Check, for instance, more examples on this web page of the e-Textbook or the latest printed version.

Comparison 05T|1.5T.

These images show a comparision of the contrast behavior of synthetic images of two brains acquired at 0.5 Tesla and 1.5 Tesla.

Breach of License Agreement. Because MR Image Expert was plagiarized illegally by a number of companies, the software is not available any more on the open market. We deeply regret this move, but we do not work and invest in free educational material for the benefit of commercial plagiators.
