摘要 目的:探讨磁共振高分辨T2WI成像技术在直肠癌术前TN分期中的诊断价值。方法:回顾性分析47例经过手术及病理证实的直肠癌病人的影像资料,比较MRI诊断结果与病理结果的差异。结果:47例T分期中正确分期40例。其中T1+2分期灵敏度为83.3%,特异度为93.1%;T3分期灵敏度为87.5%,特异度为82.6%;T4期灵敏度为80%,特异度为97.6%。N分期中正确的38例,N0灵敏度为84.6%,特异度为76.2%;N1灵敏度为76.2%,特异度为84.6%。累及环周切缘7例,灵敏度为87%。结论:磁共振高分辨T2WI成像技术有助于鉴别诊断直肠癌的TN分期及环周切缘累及情况。可以为临床合理手术方式的选择提供参考依据。
