Biliary stenoses are common complications after liver transplantation. ERCP is actually the gold standard to evaluate the bile ducts and differentiate between stenoses of the anastomosis and strictures of the ducts due to ischemia. In our study we evaluated different MRC sequences concerning their ability to diagnose and differentiate biliary strictures. Our results showed that one sequence alone can not present the whole disease. Thus, a clinical protocol to diagnose and differentiate biliary strictures should comprehend different MRC sequences to be able to compete against ERCP.
