Objective：To investigate the value of magnetic resonance cholangiopancreatography(MRCP) in the diagnosis of pancreas divisum by comparing with endoscopic retrograde cholangiopancreatography (ERCP).Methods: The MRCP and ERCP images of 8 patients with pancreas divisum were retrospectively analyzed. The diagnostic accuracy and findings by MRCP were compared with those by ERCP. Results: MRCP had a diagnostic accuracy of 87.5%（7/8） based on the result of ERCP. ERCP displayed the dominant dorsal pancreatic ducts in all 8 cases and ventral pancreatic ducts in 6 cases; MRCP also displayed the dominant dorsal pancreatic ducts in all 8 cases, but the ventral pancreatic ducts only in 3 cases.Conclusion: As a non-invasive technique,MRCP has important clinical value in the diagnosis of pancreas divisum.
