Postoperative pancreatic fistula (POPF) is a prevalent and severe complication of pancreaticoenteric anastomosis; however, its accurate preoperative prediction is challenging. Multi-frequency MR elastography-based tomoelastography can quantify pancreatic mechanical properties (stiffness and fluidity), thus further improving the predictive performance of conventional MRI for postoperative pancreatic fistulas.
