New ultrasound and magnetic resonance tests to detect cirrhosis may reduce the need for biopsies

Researchers of Mayo Clinic College of Medicine, Rochester, Minn have developed new ultrasound and magnetic resonance (MR) imaging tests which could detect liver initial stages of fibrosis (scarring) and cirrhosis, reducing the need for biopsies. The new technique, named MR elastography, is non-invasive and measures reactions to mechanical shear waves, rather than ultrasound vibrations.

The test was nearly 100 percent accurate in identifying patients with any degree of liver fibrosis, including those with mild fibrosis. The early detection of liver fibrosis is very important because when fibrosis becomes severe, it indicates the presence of cirrhosis.
