The Utility of Elastography in Discriminating Stages of Liver Fibrosis and Risk Stratification in Patients With Primary Sclerosing Cholangitis: A Systematic Review

Primary sclerosing cholangitis (PSC) is a chronic autoimmune disease involving inflammation in the liver and biliary system, manifesting as biliary strictures and cholestasis, and leading to hepatic fibrosis. Due to variable patterns of fibrosis, precise criteria for risk stratification of these patients have yet to be determined. Elasticity‐based methods are widely used to estimate the stage of liver fibrosis in PSC.
