This study is to access the differential value in Pancreatic Carcinoma (PC) and Mass-Forming focal Pancreatitis (FP) with qualitative and quantitative analysis of DCE-MRI and DWI. Pancreatic TIC types and sub-types from DCE-MRI and ADC value and tumor-to-pancreas contrast ratio of ADC value from DWI were compared between PC and FP. We found significant differences in TIC and ADC value and ADC tumor-to-pancreas contrast ratio between PC and FP. DCE-MRI and DWI were discovered to provide reliable information for differentiating PC from FP, while the combination of them can achieve a higher sensitivity and specificity.
