| Popis: | To assess the duct-road sign and tumor-to-duct ratio (TDR) in MRI for differentiating pancreatic neuroendocrine tumors (PNETs) from pancreatic ductal-adenocarcinomas (PDACs). Retrospectively reviewed MRI characteristics of 78 pancreatic masses (histopathology-proven 25 PNETs and 53 PDACs). Receiver operating characteristics with TDR and diagnostic performance of the duct-road sign for differential diagnosis were performed. The prevalence of duct-road sign in PNETs was higher than that for PDACs (84% vs 0%; P 7.7 on MRI may assist in diagnosis for PNET instead of PDAC. |
