The Basics of MR Elastography

Abstract

　Magnetic resonance elastography (MRE) is a relatively new technology for quantitatively assessing the mechanical properties of tissues. It can be considered an imaging-based virtual palpation. The purpose of this review is to introduce this technology to clinicians/technologists and summarize its basic mechanism. First, a brief overview of MRE is provided. Second, the method of MRE is explained. Finally, an example of psoas major MRE is introduced.
