CT与MRI在结直肠癌术前评估中的应用价值

Application Value of CT and MRI in Preoperatively Evaluating Colorectal Cancer

目的:探讨CT与MRI在结直肠癌术前评估中的应用价值。方法:回顾性分析2015-2019年我院收治的60例结直肠癌患者临床资料。入院后所有患者术前均行CT扫描与MRI扫描检查,以术后病理检查结果为金标准,分析CT、MRI术前单项检查与联合检查对结直肠癌T分期、N分期的诊断价值。结果:60例患者病理诊断T分期结果显示,T16例,T213例,T334例,T47例;CT检查结果显示,T1期3例,准确率为50.00%,T2期8例,准确率为61.54%,T3期27例,准确率为79.41%,T4期4例,准确率为57.14%;MRI检查结果显示,T1期5例,准确率为83.33%,T2期10例,准确率为76.92%,T3期30例,准确率为88.24%,T4期6例,准确率为85.71%。60例患者病理诊断N分期结果显示,N013例,N128例,N219例;CT检查结果显示,N0期9例,准确率为69.23%,N1期22例,准确率为78.57%,N2期15例,准确率为78.95%;MRI检查结果显示,N0期12例,准确率为92.31%,N1期26例,准确率为92.86%,N2期18例,准确率为94.74%。CT联合MRI检查诊断T分期准确率:T1100.00%、T284.62%、T391.18%和T4100.00%,N分期准确率:N0100.00%、N196.43%和N2100.00%。结论:结直肠癌患者术前T分期、N分期评估中,MRI检查准确率高于CT检查,但CT联合MRI检查准确率最高,能帮助医师在术前制定最佳治疗方案,值得临床推广。

Objective To explore the application value of CT and MRI in preoperatively evaluating colorectal cancer.Methods Retrospectively reviewed the clinical data of 60patients with colorectal cancer treated in authors'hospital(2015-2019):after admitted all the patients received CT and MR inspection,taking postoperative pathological exam.results as gold-standard,the diagnosis values on T stage and N stage of single inspection of CT and MR,as well as that of combined inspection of both were analysed.Results The pathological exam.results of T stage slowed T1,6cases;T2,13cases;T3,34cases;T4,7cases,respectively and relevantly,CT results:T1,3cases(accurate rate,50%);T2,8cases(61.54%);T3,27 cases(79.41%);T4,4cases(57.14%),meanwhile,MRI results:T1,5cases(83.33%);T2,10cases(78.92%);T3,30cases(88.24%);T4,6cases(85.71%).The pathological exam.results of N stage showed No.13cases;N1,28cases;N2,19cases,respectively and relevantly,CT results:N0,9cases(accurate rate,69.23%);N1,22cases(78.57%);N2,15cases(78.95%),meanwhile,MRI results:N0,12cases(92.31%,accurate rate);N1,26cases(92.86%);N2,18cases(94.74%).The diagnostic accurate rates on T stage by using the combined inspection of both were as T1,100.00%;T2,84.62%;T3,91.18%;T4,100.00%,meanwhile,the ones on N stage were as N0,100.00%;N1,96.43%;N2,100.00%respectively.Conclusion In preoperative staging evaluation of colorectal cancer,MRI's accurate rate is higher than CT's ones,if the combination of both the rate is more higher which is helpful to doctors making optimun treatment schema before surgery,thus is worth to be popularized clinically.
