1.5T高分辨率MRI对直肠癌术前T分期的诊断价值

Diagnostic value of 1. 5T high resolution MRI in preoperative T staging of rectal cancer

目的:探讨1.5T高分辨率磁共振成像(MRI)对直肠癌术前T分期的诊断价值。方法:回顾性分析2016年10月至2017年5月在南充市中心医院就诊的45例直肠癌患者的MRI图像,将MRI T分期结果与术后病理结果对比研究,分析高分辨率MRI对直肠癌T分期的诊断价值。结果:高分辨率MRI直肠癌T分期准确性为86.7%(39/45),经统计软件分析MRI术前T分期与术后病理T分期一致性较好(kappa=0.792,P<0.001)。结论:1.5T高分辨率MRI能够较准确地对直肠癌进行术前T分期,指导临床合理选择治疗方案。

Objective：To evaluate the diagnostic value of 1.5T high resolution magnetic resonance imaging （MRI） in preoperative T staging of rectal cancer.Methods：The MRI images of 45 patients with rectal cancer in Nanchong Central Hospital from October 2016 to May 2017 were analyzed retrospectively.The results of T staging in MRI were compared with the postoperative pathological findings，and the diagnostic value of high-resolution MRI for T staging of rectal cancer was analyzed.Results：The accuracy of T staging for rectal cancer with high resolution MRI was 86.7%（39/45），and the consistency of T staging and postoperative pathological T staging was better by statistical software analysis （kappa=0.792，P〈0.001）.Conclusion：1.5T high resolution MRI can accurately evaluate the preoperative T staging of rectal cancer and guide the rational selection of treatment protocols.
