The Diagnostic Performance of Magnetic Resonance Multi Sequence Imaging in T-staging of Colon Cancer
Objective Explore the diagnostic performance of magnetic resonance multi sequence imaging(MRI)in T-staging of colon cancer(CC).Methods 32 patients with colon cancer admitted to Huaihe Hospital of Henan University from January 2022 to December 2022 were retrospectively collected.All colon cancer patients underwent MRI examination before surgery.The whole abdomen and liver were scanned using T2 weighted imaging(T2WI)fast spin echo sequence(Coronal plane,axial,Sagittal plane),diffusion weighted imaging(DWI)sequence(axial),and contrast enhanced T1 weighted imaging(T1WI)sequence(Coronal plane).Record the location of the tumor,the depth of intestinal wall infiltration,and whether it invades the serosal layer,and compare with postoperative pathological results.The receiver operating characteristic(ROC)curve was used to analyze the diagnostic efficacy of T2WI sequence and contrast-enhanced T1WI sequence in preoperative T staging of CC patients in MRI.Results The accuracy,sensitivity,and specificity of T2WI sequence in MRI for T staging of colon cancer patients were 81.25％,84.21％,and 66.67％,respectively.In addition,the accuracy,sensitivity,and specificity of enhanced T1WI sequence in MRI were 93.75％,94.12％,and 75％,respectively.Conclusion MRI is a potential and valuable imaging method for preoperative T-staging detection in colon cancer patients,and T1WI has higher diagnostic value.
