MSCT及高场强MRI检查在直肠癌术前分期诊断中的应用价值对比

Comparison on Application Value between MSCT and High Field MRI in the Diagnosis of Preoperative Staging of Rectal Cancer

目的探讨多层螺旋CT(MSCT)及高场强磁共振成像(MRI)在直肠癌术前分期的应用价值。方法回顾性分析本院2017年6月至2018年9月收治的120例直肠癌患者临床资料,以手术病理结果为金标准,对比分析MRI及MSCT检查对直肠癌TMN分期准确率。结果MSCT检查直肠癌T期的准确率为85.83%,N期的准确率为89.17%;MRI检查直肠癌T期的准确率为97.50%,N期的准确率为99.17%,MRI对直肠癌的分期准确率显著高于MSCT对直肠癌的分期准确率,差异有统计学意义(P<0.05)。结论采用MRI检查和MSCT检查均可有效显示直肠癌的影像学特点,但是MRI检查对直肠癌术前分期的准确率显著高于MSCT检查,值得在直肠癌治疗前分期诊断方面进行推广。

Objective To investigate the application value between MSCT and high field MRI in preoperative staging of rectal cancer.Methods The clinical data of 120 patients with rectal cancer admitted to our hospital from June 2017 to September 2018 were retrospectively analyzed.Based on the criteria of TNM staging of rectal cancer and the results of MRI and MSCT.The accuracy rate of TMN staging of rectal cancer by MRI and MSCT was compared and analyzed with the surgical and pathological results as the gold standard.Results The accuracy of MSCT in the diagnosis of T staging of rectal cancer was 85.83%,the accuracy in the diagnosis of N staging of rectal cancer was 89.17%,the accuracy of MRI in the diagnosis of T staging of rectal cancer was 97.50%,and the accuracy in the diagnosis of N staging of rectal cancer was 99.17%.The accuracy of MRI for staging of rectal cancer was significantly higher than that of MSCT.The difference was statistically significant(P<0.05).Conclusion MRI examination and MSCT examination can effectively display the imaging features of rectal cancer,but the accuracy of MRI examination for preoperative staging of rectal cancer is significantly higher than that of MSCT.It is worthy of promotion in the diagnosis of preoperative staging of rectal cancer.
