Measurement of Liver Elasticity with Acoustic Radiation Force Impulse (ARFI) Technology: An Alternative Noninvasive Method for Staging Liver Fibrosis in Viral Hepatitis

Abstract

This study underscores the usefulness of ARFI as a quick method for assessing liver fibrosis or cirrhosis in patients with HBV or HCV. ARFI measurements of the liver should be performed via an intercostal access. Increasing ARFI velocities correlate with higher degree of hepatic fibrosis.
