Abstract

Abstract

Objective To investigate the clinical value of contrast-enhanced CT and MRI in preoperative TNM staging of pancreatic cancer. Methods A retrospective analysis was performed on 62 pancreatic cancer patients diagnosed by surgical pathology from January 2019 to December 2021 in the First Affiliated Hospital of Kunming Medical University. The preoperative enhanced CT and MRI images, operation status and postoperative pathological results were analyzed. All the findings were reviewed by two senior radiologists separately for preoperative imaging staging. The preoperative TNM staging of the two methods were compared with the surgical and pathological results. Results The overall accuracy of contrast-enhanced CT and MRI in TNM staging of pancreatic cancer were 86.96% （40/46）and 89.13% （41/46）in T stages, 78.57% （33/42）and 73.81% （31/42） in N stages, 96.77% （60/62） and 98.39% （61/62）in M stages, both had good consistency in T stages, moderate consistency in N stages and strong consistency in M stages compared with surgical and pathological results. There was no significant difference between the two methods in the accuracy of preoperative TNM staging （P > 0. 05）. Conclusion Enhanced CT and MRI have a good correlation between preoperative TNM staging evaluation and surgical pathological results of pancreatic cancer, which can provide a reference for preoperative evaluation and guide treatment decision making for clinicians, and have good clinical application value.
