摘　　要：目的探究术前结肠癌T分期诊断采用磁共振(MRI)、多层螺旋CT(MSCT)与术后病理诊断一致性。方法对我院2016年6月至2019年6月期间收治92例结肠癌患者相关资料予以回顾性分析,患者在手术前均接受MRI以及MSCT检查,其后接受手术进行治疗,并进行术后病理检查,评估MRI及MSCT对术前结肠癌T分期诊断与术后病理诊断一致性。结果 MRI诊断结肠癌T1-2、T3以及T4分期准确率分别为98.91%、93.48%以及94.57%,与术后病理结果Kappa为0.975、0.870、0.806;MSCT诊断结肠癌T1-2、T3以及T4分期准确率分别为90.22%、79.35%、89.13%,与术后病理结果Kappa为0.775、0.587、0.670;MRI诊断结肠癌T分期准确率为93.48%(86/92),MSCT诊断结肠癌T分期准确率为79.35%(73/92);两种方式诊断结肠癌T分期准确率存在统计学意义(χ2=7.823,P<0.05)。结论 MRI与MSCT均可用于术前结肠癌T分期诊断,但MRI诊断与术后病理一致性高,准确率好。Objective To explore the consistency between magnetic resonance imaging (MRI),multi-slice spiral CT (MSCT) and postoperative pathological diagnosis for preoperative T staging of colon cancer.Methods The relevant data of 92 patients with colon cancer who were admitted to the hospital between June 2016 and June 2019 were retrospectively analyzed.All patients completed MRI and MSCT examinations before surgery,and then they were treated with surgery.Pathological examination was performed after surgery.The consistency between MRI,MSCT and postoperative pathological diagnosis for preoperative T staging of colon cancer was assessed.Results The accuracy rates of MRI for diagnosis of colon cancer in T1-2,T3 and T4 stages were 98.91%,93.48% and 94.57%,respectively.Compared with postoperative pathological results,the corresponding Kappa values were 0.975,0.870 and 0.806,respectively.The accuracy rates of MSCT for diagnosis of colon cancer in T1-2,T3 and T4 stages were 90.22%,79.35% and 89.13%,respectively.Compared with postoperative pathological results,the corresponding Kappa values were 0.775,0.587 and 0.670,respectively.The accuracy rates of MRI and MSCT for diagnosis of T stages of colon cancer were 93.48% (86/92) and 79.35% (73/92),respectively (χ2=7.823,P<0.05).Conclusion Both MRI and MSCT can be used for preoperative diagnosis of T stages of colon cancer,but MRI diagnosis has high consistency with postoperative pathology and good accuracy.
