目的评价ＭＲＩ在喉癌术前Ｔ分期中的价值。方法对５９例喉癌的ＭＲＩ资料进行回顾性分期，并与纤维喉镜及手术病理对照。结果ＭＲＩ对各期喉癌分期的准确性分别是：Ｔ１：９５％（２０／２１），Ｔ２：８８％（１５／１７），Ｔ３：８５％（１１／１３）Ｔ４：１００％（８／８）。纤维喉镜分期的准确性是：Ｔ１：９１％（１９／２１），Ｔ２：８８％（１５／１７），Ｔ３：４７％（８／１３），Ｔ４：１３％（１／８）。结论ＭＲＩ能准确判断会厌前间隙（ＰＥＳ）、喉旁间隙（ＰＧＳ）浸润及软骨破坏，因而可显著提高喉癌术前分期的准确性，对临床治疗方案选择具有重要意义。
Objective To evaluate the value of MRI in preoperative T stage of laryngeal carcinoma. Methods The MRI data of 59 cases of laryngeal carcinoma were retrospectively staged and compared with the fibrolaryngoscope and surgical pathology. Results The accuracy of MRI in staging laryngeal cancer was T1: 95% (20/21), T2: 88% (15/17), T3: 85% (11/13), T4: 100% 8). The accuracy of fiberopharyngeal staging was T1: 91% (19/21), T2: 88% (15/17), T3: 47% (8/13), and T4: 13% (1/8). Conclusion MRI can accurately determine the anorectal anterior gap (PES), laryngeal space (PGS) infiltration and cartilage destruction, which can significantly improve the accuracy of preoperative staging of laryngeal cancer, the choice of clinical treatment program is of great significance.
