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 90 minutes which take place once a week and a self-assessment test. Thus, the course extends over a period of 7 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);
• use the right measurement sequence for your clinical questions;
• optimise your MR examination (measurement protocol, sequence timing, etc.);
• verify image contrast by modifying measurement sequence or by applying contrast agents;
• interpret MR images back to tissue components and functional activities;
• understand advanced MRI techniques such as MR angiography, dif
fusion imaging, perfusion sequences etc.
• ensure safe application of MRI by knowing the involved hardware components and the safety risks



Course Details:
The course consists of 7 modules, 90 minutes each, including time for questions.
The lecture material will be uploaded approx. 1-3 days prior to the respective module. Only watermarked and secured pdf documents will be available for participants. The webinar itself will not be provided on demand.
It is recommendable to use a headset for the interactive part of the course, but you can also log-in by phone.
A confirmation of attendance will be provided at the end of the course. Please be informed that you have to be present 70% (5 out of 7 modules) of the course in order to receive a confirmation of attendance. We would appreciate to receive a short notification in case you will not be able to attend one of the modules.
The webinar will consist of a power point presentation shown via computer and a live talk of the speaker. After the 60-minute talk there will be a question/answer session of approx. 30 min. Be aware that you will automatically be muted for the webinar. There will be a 'raise the hand' function to ask questions during the webinar. This function will be carried out by the speaker and you will be able to ask your question as soon as you are unmuted by the presenter. There will also be a 'write your question' option. These questions will be answered at the end of the module.
