Interobserver agreement and prognostic value of image-based scoring systems in patients with primary sclerosing cholangitis.

Background: Primary sclerosing cholangitis (PSC) is a cholestatic liver disease that progresses to cirrhosis and liver failure. The Anali and Amsterdam scores are based upon imaging features on MRI and ERCP, respectively.

Aims: We aimed to compare the interobserver variability and performances of these scores.
