Pancreatic cancer (PC) occurs a histopathologically stronger pancreatic fibrosis compared to other non-PC. The risk factors of postoperative pancreatic fistula (POPF) were reported as soft or normal pancreatic parenchyma, and ampullary or duodenal disease. In this study, in patients with non-PC, frequency of POPF was greater due to lower grade of pancreatic fibrosis, and our results suggest that T1 signal and ADC value of the pancreas may link to the POPF. The T1 signal and ADC value of the pancreas may be a potentially useful imaging biomarker for the assessment of pancreatic fibrosis and POPF.
