Magnetic Resonance Elastography (MRE) is an emerging MRI technology that enables in vivo quantitative assessment of tissue stiffness for applications ranging from staging of liver cirrhosis to characterizing the onset of Alzheimer's disease. In this course, the history and development of MRE will be overviewed, the key enabling technologies for MRE (e.g., pulse sequences, image processing methods) will be described, and several clinical applications where MRE has proven beneficial will be discussed in detail.

Target Audience
Physicists and Clinicians with a solid basic understanding of MRI who are interested in learning about the history, technical foundations, and clinical applications of MR elastography.

Educational Objectives
Upon completion of this course, participants should be able to:

-Describe the technical foundations of MR Elastography;
-Identify key clinical applications where MRE can be used; and
-Compare and contrast MRE to other quantitative MRI techniques.

Overview & History
Richard Ehman
This presentation provides a high-level survey of the rationale, physical basis, and current status of  MR Elastography, as well as a perspective on the development of ultrasound and MRI-based elastography technologies over the last several decades. 

MRE Technology - permission withheld
Ingolf Sack
Magnetic resonance elastography (MRE) is a phase-contrast based MRI technique that measures displacement due to propagating mechanical waves, from which mechanical material properties such as shear modulus can be recovered. MRE has high potential as a quantitative, physics-based imaging modality for soft-tissue characterization in many clinical applications. This talk gives an overview on the technological aspects of MRE including driver technology, imaging sequences and reconstruction methods.
