Two new studies examine non-invasive ways to determine liver fibrosis and cirrhosis

An enhanced version of the Original European Liver Fibrosis panel was found to have good diagnostic accuracy for fibrosis in patients with non-alcoholic fatty liver disease. Conversely, transient elastography was unreliable for detecting cirrhosis in patients with acute liver damage. The studies are published in the February issue of Hepatology, a journal by John Wiley & Sons on behalf of the American Association for the Study of Liver Diseases (AASLD). The articles are also available online at Wiley Interscience.
