Core Tip

Core tip: Magnetic resonance elastography (MRE) is a non-invasive technique for probing the mechanical properties of biologic tissues. The three main steps involved in the MRE technique include the production of mechanical waves in soft tissues, the adoption of a modified phase-contrast MR sequence to image wave motion, and the application of an inversion algorithm to convert the wave image into an elastogram. MRE has received validation for the non-invasive assessment and grading of fibrosis in chronic liver disease patients. MRE also has potential diagnostic applications in other organ systems and may help further the understanding of disease processes.
