Many studies have shown multi-echo chemical-shift-encoded magnetic resonance imaging (CSE-MRI) has good performance for the evaluation of fat and iron in liver. However, the relevant studies in pancreas are fewer. We found that pancreatic PDFF and R2* estimated by T2* corrected multi-echo CSE-MRI showed a moderate correlation with 1H-MRS results in patients undergoing pancreatic resection. In addition, our study showed that pancreatic PDFF was not to be significantly associated with clinically relevant postoperative pancreatic fistula.
