Magnetic resonance elastography

Overview

Magnetic resonance elastography (MRE) is a technology that combines MRI imaging with low-frequency vibrations to create a visual map (elastogram) that shows stiffness of body tissues.

Currently, MRE is used to detect stiffening of the liver caused by fibrosis and inflammation in chronic liver disease. But MRE is also being evaluated as a noninvasive way to diagnose diseases in other parts of the body.

MRE technology was invented at Mayo Clinic. The test is available there and at over 1,000 other centers around the world. It's usually done as part of a conventional MRI exam.
