Pancreatic duct stenosis: Differential diagnosis between malignant and benign conditions at secretin-enhanced MRCP

Purpose To define imaging criteria of benign and malignant nature in patients with main pancreatic duct (MPD) stenosis. Materials-methods S-MRCPs of 35 patients with pancreatitis and 14 with adenocarcinoma were evaluated. Results Adenocarcinoma caused higher prevalence of complete stenosis (14/14–100% vs 17/35–49%), dilated side-branches (14/14–100% vs 18/35–51%) and lower prevalence of duct-penetrating sign (0/14–0% vs 31/35–89%). The number of...
