What you can expect

By Mayo Clinic Staff

MRE is usually done as part of a conventional MRI examination. A standard MRI liver examination takes 30 to 45 minutes. The MRE portion of the test takes less than five minutes.

In MRE, a small pad is placed on the surface of your body. The pad emits low-frequency vibrations that pass through your liver. The speed at which the vibrations pass through the liver is measured. Vibrations travel faster through stiff tissue.
