PurposeTo compare imaging features of pancreatic metastases (PM) with those of pancreatic ductal adenocarcinomas (PDAC).MethodsCT and MR scans of 24 patients with 54 PM and 30 patients with PDAC were reviewed to evaluate the imaging features, which were compared by using a Chi square test.ResultsWe found a statistically significant difference between PM and PDAC based on location (P < 0.001), margins (P < 0.001), arterial enhancement (P = 0.004), rim enhancement (P < 0.001), pancreatic duct dilatation (P = 0.01), common bile duct dilatation (P = 0.003), vascular involvement (P = 0.02), parenchymal atrophy (P < 0.001), peripancreatic fluid (P = 0.03).ConclusionImaging features might be helpful to differentiate PM from PDAC.
