Abstract
Purpose: To compare imaging features of pancreatic metastases (PM) with those of pancreatic ductal adenocarcinomas (PDAC). Methods: CT 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. Results: We 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). Conclusion: Imaging features might be helpful to differentiate PM from PDAC.
