摘　　要：目的对比研究MRI与CT增强扫描对右半结肠癌术前T分期的应用价值。方法回顾性分析经病理证实为右半结肠癌的患者50例,所有的病例同时行MRI及CT增强扫描,并进行T分期及统计学分析。结果术前CT增强扫描T分期准确度为78%(39/50),Kappa值为0.663(P=0.000),术前MRI增强扫描T分期准确度为84%(42/50),Kappa值为0.754(P=0.000),二者与病理诊断结果均有较强的一致性。结论MRI及CT增强扫描均能够准确地对右半结肠癌T分期进行评估,对临床治疗方案的制定具有重要意义,MRI及CT检查各有优缺点,术前检查的选择应根据患者的自身情况决定。Objective To compare the value of MRI and CT enhanced scan in preoperative T staging of the right side of colon cancer.Methods Totally 50 patients with pathologically proven the right side of colon cancer were included.All cases underwent enhanced MRI and CT scan,and T staging and statistical analysis were performed.Results Preoperative CT enhanced scan T staging accuracy was 78%(39/50),Kappa value was 0.663(P=0.000),preoperative MRI enhancement scanning T staging accuracy was 84%(42/50),Kappa value was 0.754(P=0.000),CT and MRI both had good consistency with pathological diagnosis.Conclusion MRI and CT enhanced scan can be accurate to evaluate the right colon cancer T staging,and very helpful in the clinical treatment plan formulation.MRI and CT each have advantages and disadvantages,the choice of preoperative examination shall be determined according to the patients'condition.
