Aim: To assess the prognostic role of MRC in the follow-up of patients with primary sclerosing cholangitis (PSC). Methods: The study included 52 consecutive PSC patients who underwent MRC with Gd-EOB-DTPA at the baseline and at every 2-year follow-up. The prognostic value of the MRC was assessed using an adaptation of the original Amsterdam classification validated for endoscopic retrograde cholangiography. Images were scored from I to V, based on the severity of biliary strictures and dilations. Results: The mean follow-up was 122.3±8.7 months, and a total of 89 MRC was collected. Twenty-three patients (44.2%) had a final MRC score ≤III, while for 29 (55.8%) it was >III. Patients with MRC scores >III had significantly higher alkaline phosphatase levels, more severe liver stiffness, a higher rate of biliary complications in the baseline than patients with MRC scores ≤III. At 2-year follow-up, MRC scores >III correlated significantly with serum transaminases, GGT, and alkaline phosphatase levels. Multivariate analysis showed that the occurrence of biliary complications and the indication for a liver transplant were significantly associated with a final MRC score >III. Conclusions: MRC scores based on image features and contrast enhancement pattern after Gd-EOB-DTPA administration can provide prognostic information in PSC.
