Overview
Brain MRI continues to be a rapidly evolving area, and it sometimes seems as if every day a new MRI technique is introduced for imaging the brain. However, how do these "hot" novel techniques work, why would we want them at all, and are they ready to be clinically implemented or still within the realms of science? In this Sunrise course, four novel and promising quantitative MRI techniques used for brain imaging will be discussed, from basic principles and technical details to (potential) clinical applications.

Target Audience
Scientists either searching for a new research field or just staying up-to-date with the latest developments in brain MRI; clinicians who wish to understand new MRI techniques, learn how they can be adapted to the brain, and how they might be applicable in clinical practice.

Educational Objectives
As a result of attending this course, participants should be able to:
- Describe the basics of MR thermometry, sodium imaging, MR elastography, and 4D flow quantification;
- Give examples of clinical cases in which these techniques can be useful; and
- Identify the limitations of each technique.

	08:30		Brain MR Elastography in the Clinic: Indications & Challenges View the Presentation Katharina Schregel Magnetic resonance elastography (MRE) is an innovative MRI technique that allows for the non-invasive quantification of biomechanical brain tissue properties. Neuro-oncologic, neuroinflammatory and neurodegenerative diseases affect the organization and composition of brain tissue and hence its biomechanical properties. Thus, MRE is a promising tool for the evaluation of brain pathologies rendering information complementary to other imaging methods. Even though research studies demonstrated the potential of MRE to improve neuroradiological diagnosis and follow-up of various brain pathologies, some challenges remain before this technique can be used in the clinical routine.
