摘　　要：目的探讨磁共振多序列成像(magnetic resonance imaging,MRI)在结肠癌(colon cancer,CC)T分期的诊断性能。方法回顾性收集河南大学淮河医院于2022年1月至2022年12月收治的结肠癌患者32例。所有结肠癌患者术前均接受MRI检查。依次使用T2加权成像快速自旋回波序列(T2 weighted imaging,T2WI)快速自旋回波序列(冠状面、轴面、矢状面)、扩散加权成像序列(diffusion weighted imaging,DWI)序列(轴面)及对比增强T1加权成像(T1 weighted imaging,T1WI)序列(冠状面)完成对全腹部和肝脏的扫描。分别对肿瘤的位置、肠壁浸润深度及是否侵犯浆膜层进行记录,并与术后病理结果进行比较。采用受试者工作(receiver operating characteristic,ROC)曲线分析MRI中T2WI序列、对比增强T1WI序列对术前CC患者T分期的诊断效能。结果MRI中T2WI序列对结肠癌患者T分期的准确性、敏感性、特异性分别为81.25%,84.21%,66.67%。此外,MRI中增强T1WI序列的准确性、敏感性、特异性分别为93.75%,94.12%,75%。结论MRI是结肠癌患者术前T分期检测的一种潜在的和有价值的影像学方法,且T1WI具有更高的诊断价值。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.
