Imaging Features of Rectal Fascia in MSCT and MRI and Its Predictive Value for Preoperative T Staging and Postoperative Recurrence of Rectal Cancer

Objective To investigate the imaging features of rectal fascia in MSCT and MRI and its predictive value for preoperative T staging and postoperative recurrence of rectal cancer.Methods 88 patients with rectal cancer admitted to our hospital from July 2015 to July 2018 were enrolled.The clinical data of all patients were collected.The pathological examination results were used as the standard to compare the accuracy of MSCT and MRI in the diagnosis of infiltration grading of the rectal fascia.Results To compare the diagnostic accuracy of MSCT and MRI for T-stage,the total accuracy of MRI for infiltration was 92.04%(81/88),the accuracy for stage T1-2 was 82.35%(14/17),the accuracy for stage T3 was 96.77%(30/31),and the diagnostic accuracy for stage T4 was 92.50%(37/40).The total accuracy of MSCT scan for infiltration was 81.81%(72/88),the accuracy for stage T1-2 was 70.58%(12/17),the accuracy for stage T3 was77.41%(24/31),and the diagnostic accuracy for stage T4 was 90.00%(36/40).Compared with the overall diagnostic accuracy of MSCT,MRI was more accurate in T staging(χ²=4.051,P=0.044).Conclusion MSCT and MRI are used to diagnose the degree of mesangial infiltration of rectal cancer before operation,MRI can provide more reliable imaging information for clinical treatment and prognosis.
