MRI has higher accuracy in the preoperative diagnostic analysis of rectal cancer compared with 256-slice CT
Objective To investigate the application value of 256-slice CT and MRI in the preoperative staging diagnosis of rectal cancer.Methods A total of 86 patients with rectal cancer confirmed in the First Affiliated Hospital of Bengbu Medical University from August 2019 to May 2023 were collected in the study,the postoperative pathological findings served as the gold standard,and all patients underwent a multi-layer spiral CT scan and functional MRI imaging before surgery.It was done to comprehensively evaluate the diagnostic accuracy of MRI and 256-slice CT for preoperative T staging and lymph node metastasis of rectal cancer.Results The postoperative results of T staging are as follows:37,39,10 cases were identified as stage T1-2,T3 and T4,respectively.The MRI accurately diagnosed 33,35,9 cases of stage T1-2,T3 and T4,respectively,while CT accurately diagnosed 27,29,8 cases of stage T1-2,T3 and T4,respectively.The pathological results demonstrated that 62 cases exhibited evidence of lymph node metastasis,50 cases exhibited positive findings on MRI and 36 cases exhibited positive findings on CT.In accordance with the pathological gold standard,the diagnostic sensitivity,specificity and accuracy of MRI in detecting stage T1-2,T3,T4 and lymph node metastasis of rectal cancer were superior to those of CT.Furthermore,the diagnostic outcomes of MRI in each stage were consistent with the pathological results,and the Kappa value was higher than that of CT.Conclusion Compared with 256-slice CT,MRI is more accurate in the preoperative diagnostic analysis of rectal cancer,providing more precise imaging reference materials for patients.
