Elastography

What is elastography?

Elastography, also known as liver elastography, is an imaging test to check for liver fibrosis. Fibrosis is a disease that reduces blood flow to and from the liver. This can lead to the accumulation of scar tissue. If left untreated, fibrosis can lead to serious liver problems. These include cirrhosis, liver cancer and liver failure. However, early diagnosis and treatment can reduce or reverse the effects of fibrosis.

There are two types of liver elastography tests.

Ultrasound elastography, also known as Fibroscan, is a brand name for ultrasound equipment. This test uses sound waves to measure the stiffness of liver tissue. Stiffness is a hallmark of fibrosis.

A test that combines MRE (Magnetic Resonance Elastography), ultrasound technology, and Magnetic Resonance Imaging (MRI). MRI is a procedure that uses powerful magnets and radio waves to create images of internal organs and structures. During the MRE test, a computer program creates a visual map showing liver stiffness.

Elastography testing can be used in place of liver biopsy. This is a more invasive test that involves removing some liver tissue for testing.

Other Names: Liver Elastography, Transient Elastography, Fibroscan, MR Elastography

What is it for?

Elastography is used to diagnose fatty liver disease (FLD) and fibrosis. FLD is a disease in which fat builds up in the liver. This fat can lead to cell death and fibrosis.
