目的:探讨3.0T高分辨率MRI在直肠癌术前T分期中的价值。方法:收集我院结直肠外科手术治疗的95例直肠癌病例,术前行MRI检查,与术后病理对照,分析MRI T分期与病理T分期的一致性。结果:T分期总诊断正确率为89.5%(85/95),各期诊断正确率分别为T1~T2期90.5%(86/95)、T3期89.5%(85/95)、T4期98.9%(94/95)。MRI术前T分期与术后病理T分期具有较强的一致性(Kappa=0.764,P=0.000)。结论:3.0T高分辨率MRI可以较准确的进行术前T分期。
Abstract
Objective: To evaluate the value of 3.0T high resolution MRI in preoperative T staging of rectal cancer. Methods: Ninety-five cases of rectal cancer were taken into the study. All of them had a rectum MRI before surgery. The results of MRI for T staging were compared with that of histopathology. Result: The accuracy rate was 89.5% for T staging in total, 90.5% for T1~T2, 89.5% for T3, 98.9% for T4. A statistic analysis indicated that preoperative MRI for T staging was better consistent with pathologic T staging(Kappa=0.764, P=0.000). Conclusion: Preoperative 3.0T high resolution MRI may make an exact T staging.
