目的：探讨 MRI 在喉癌术前诊断、分期中的临床应用价值。方法：对 1 14 例行电子喉镜检查并经病理学证实为喉癌的患者行术前 MRI 扫描，根据图像资料判断肿瘤侵及范围及判断有无淋巴结转移；同时进行术前分期、分型，并与术后病理分期、分型对照研究。结果：术前 MRI T1 期 27 例，其中 25 例经病理证实为 T1 期， 2 例为 T2 期，准确率为 92.6%；术前 MRI T2 期 39 例，其中经病理证实 35 例为 T2 期， 3 例 T1 期， 1 例 T3 期，准确率为 89.7%；术前 MRI T3 期 29 例，其中经病理证实 25 例为 T3 期， 4 例 T2 期，准确率为 86.2%；术前 MRI T4 期 17 例，其中经病理证实 15 例为 T4 期， 2 例 T3 期，准确率为 88.2%； MRI 术前 T 分期总准确率为 87.7%。 N1 期准确率为 81.8%， N2 期准确率为 94.1%。结论： MRI 图像能很好地显示喉癌肿块的侵及范围及淋巴结转移等，对喉癌的术前分期、分型及制定合理的手术方案具有指导意义。

英文摘要:

Objective:To investigate the clinical value of pretreatment surgical magnetic resonance images (MRI) in the preoperative staging of laryngeal carcinoma.Methods:1 14 patients with laryngeal carcinoma diagnosed by electrical laryngoscope were studied by pretreatment surgical MRI examinatio. According to the images the tumor and lymphadenopathy were investigated, and the classification and staging of tumor were compared with pathological results.Results:27 cases of T1 were confirmed by MRI, in which 25 cases were confirmed by pathology; 2 cases were T2, and the accuracy of T1 staging was 92.6%; 39 cases of T2 were confirmed by MRI, in which 35 cases were confirmed by pathology, 3 cases were T1, 1 case was T3, and the accuracy of T2 staging was 89.7%; 29 cases of T3 were confirmed by MRI, in which 25 cases were confirmed by pathology, 4 cases were T2, and the accuracy of T3 staging was 86.2%; 1 7 cases of T4 were confirmed by MRI, in which 1 5 cases were confirmed by pathology, 2 cases were T3, and the accuracy of T4 staging was 88.2%, and the accuracy of T staging was 87.7%. In preoperative N staging, N1 was 81.8%, while N2 was 94.1%.Conclusion:MRI can display tumor infiltration and lymph node metastasi, which could be considered as a helpful diagnostic method that can contribute to the preoperative staging of laryngeal tumor and further clinical decision made in these patients.
