摘　　要：目的探讨MRI对直肠癌术前评估的价值。方法选取84例行外科手术治疗的直肠癌患者的MRI、病理、临床资料。用卡方检验评价MRI对诊断肿瘤T分期、N分期、环周切缘(CRM)受累情况、壁外血管浸润的准确性,用配对t检验评估MRI分析病灶与齿状线位置关系的准确性。结果MRI可较准确地评估对诊断肿瘤T分期、N分期、环周切缘受累情况、壁外血管浸润状态(P<0.01),可大致评估低位直肠癌病灶距齿状线距离(P>0.05)。结论MRI可较准确地评估对诊断肿瘤T分期、N分期、环周切缘受累情况、壁外血管浸润状态。受测量习惯、测量误差、肠管走行等因素的影响,MRI可大致评估病灶距齿状线距离,且测量误差在外科可接受范围内。MRI为临床手术选择及术前评估提供了有价值的影像学依据。Objective To explore the value of MRI in the diagnosis of rectal cancer.Methods We retrospectively analysed 84 patients’clinical information,MRI images and pathology information from the second affiliated hospital of Kunming Medical University,evaluated the accuracy of MRI in diagnosing T stage,N stage,CRM status,EMVI status by chi-square,and evaluated the distance from lower edge of the tumor to anal margin by paired t test.Results MRI can accurately evaluate the T stage,N stage,CRM status,EMVI status(P<0.01),and roughly evaluate the distance from lower edge of the tumor to anal margin(P>0.05).Conclusion MRI can accurately evaluate the T stage,N stage,CRM status,EMVI status,and roughly evaluate the distance from lower edge of the tumor to anal margin affected by measurement habits,measurement errors,intestinal deformation and other factors.We could get the conclusion that MRI provides valuable imaging reference for clinical surgical selection and preoperative evaluation.
