喉及下咽癌的MRI评价(兼与CT比较)

目的：探讨MRI对喉及下咽癌术前分期及术后评价中的临床应用价值。方法：26例喉及下咽癌患者(原发性肿瘤23例、术后复发3例)进行MRI扫描，分析其MRI表现，将结果与手术病理及CT扫描作比较。结果：MRI能较好地显示肿瘤的部位、大小及其侵犯范围。MRI对术前肿瘤分期及诊断颈部淋巴结转移的准确性为91％。高于CT扫描的87％及83％。结论：MRI扫描喉及下咽癌术前分期及术后评价有较大的帮助。

Laryngeal and hypopharyngeal carcinomas:study of MRI (also compared with CT)

Objective:To evaluate the clinical applications of MRI in preoperative tumor staging and the postoperative condition evaluation of laryngeal and hypopharyngeal carcinoma.Methods:The MRI scans were performed in 26 patients with laryngeal or hypopharyngeal carcinoma (primary tumor 23 cases and postoperative evaluation 3 cases), and the MRI features of laryngeal or hypopharyngeal carcinoma were investigated. The results were compared with the findings of surgery and CT scans.Results:MRI could reliably exhibit the location, size, and extent of the laryngeal and hypopharyngeal carcinoma. Both the accuracy in preoperative tumor staging and diagnosis of metastatic lymph nodes were 91% and respectively, and were higher than that of CT scans (87% and 83%). MRI was useful in detecting the laryngeal cartilage invasion, metastatic lymph nodes and postoperative tumor recurrence.Conclusion:MRI can provide useful information about the laryngeal and hypopharyngeal carcinoma in preoperative tumor staging and the postoperative condition evaluation.
