目的 评价高场MRI在喉癌术前分期中的价值。方法 对28例喉癌患者的MRI资料进行回顾性分析,并与手术病理分期相对照。结果 MRI对各期喉癌的准确率分别是T1:90％,T2:80％,T3:83％,T4:100％。MRI分期总准确率为89％。结论高场MRI通过不同加权像的对比和从多角度准确显示肿瘤的部位形态及浸润范围,提高了喉癌术前分期的准确性。
Objective To evaluate the value of high field MRI in the preoperative staging of laryngeal cancer. Methods The MRI data of 28 patients with laryngeal cancer were retrospectively analyzed and compared with the pathological stage of surgery. Results The accuracy rates of MRI for all stages of laryngeal carcinoma were T1: 90%, T2: 80%, T3: 83% and T4: 100% respectively. The total accuracy of MRI staging was 89%. Conclusion High-field MRI improves the accuracy of preoperative staging of laryngeal carcinoma by contrasting different weighted images and accurately displaying the tumor’s site morphology and infiltration range from multiple perspectives.
