Application Value of Transrectal Biplanar Ultrasound Combined with MRI in Preoperative T Staging of Rectal Cancer
Objective To explore the application value of transrectal biplanar ultrasound combined with MRI in preoperative T staging of rectal cancer.Methods A total of 90 patients with rectal cancer admitted to our hospital from January 2021 to January 2023 were selected as the study objects.All patients underwent transrectal biplanar ultrasound combined with MRI.To evaluate the value of transrectal biplanar ultrasound combined with MRI in preoperative T staging of rectal cancer using pathological results as the gold standard.Results In 90 cases of rectal cancer patients,based on the"gold standard",10 cases of postoperative stage PT1;PT2 was found in 23 cases.PT3 was found in 38 cases.There were 19 cases with PT4,and the accuracy of UT1 diagnosis was 60.00%by transrectal biplanar ultrasound alone.The accuracy of UT2 was 65.21%.UT3 accuracy was 81.57%;The accuracy of UT4 was 84.21%;The overall accuracy was 90.00%.The accuracy rate of T1 diagnosis by MRI alone was 70.00%.T2 accuracy was 69.56%;The accuracy of T3 was 86.84%;T4 accuracy rate was 78.94%;The overall accuracy was 88.88%.The accuracy rate of UT1 was 50.00%.UT2 accuracy 78.26%;The accuracy of UT3 was 76.31%.The accuracy of UT4 was 89.47%.The overall accuracy was 91.11%.The sensitivity,specificity and accuracy of the combined detection of the two methods were higher than that of the single detection of transrectal double-plane ultrasound and MRI,and the detection rate of rectal cancer was higher and the diagnostic value was better,with statistical difference(P<0.05).Conclusion The application of transrectal biplanar ultrasound combined with MRI in the preoperative staging diagnosis of rectal cancer has high accuracy,and is of great significance for the formulation of surgical plan and the prognosis of patients,and is worthy of clinical application
