eLearning: Basic Course on Applied MR Techniques

The eLearning course will take place in autumn 2018. Furthermore, the course extends over a period of seven consecutive weeks consisting of seven modules taking place always at 6 pm (CET) on the following Mondays:


Course Organiser:
Eva Scheurer



The aim of this course:

The course is aimed at those of you who have no or little physical and mathematical background, but would like to understand the process of image formation and the sequences of usual clinical MR imaging. The course consists of 7 modules of 60 minutes which take place once a week and a selfassessment test. Thus, the course extends over a period of 8 weeks. Each module consists of a presentation in form of a live lecture given by experienced teachers, and additionally offers direct interaction with the speaker with question/answer time at the end of each module. The presentations can be followed on any computer with internet access. The course is particularly aimed at medical doctors (e.g. residents in radiology), biologists or technicians who work with MRI or have an interest in using MRI for research. Participants do not need previous experience in MR techniques and MR physics.

Goals of the course:

Attendance at the Basic Course on Applied MR Techniques
will enable you to:
  • profoundly understand signal and contrast generation in MR images at different conditions (morphological, biophysical
  • and technical);
  • understand basic principles of image contrast and image formation;
  • use basic clinical sequence for your questions and enhance tissue contrast by modifying parameters and using contrast
  • agents;
  • interpret MR images back to tissue components and functional activities;
  • ensure safe application of MRI by knowing the involved hardware components and basic safety risks
