目的:探讨CT、MRI对喉癌及下咽癌喉外侵犯范围的价值。方法:回顾性分析33例喉及下咽癌喉外侵犯的CT、MRI表现,根据CT、MRI征象判断肿瘤的喉外侵犯范围,并将此结果与手术病理结果相对照。结果:CT、MRI判断肿瘤喉外部位或结构侵犯的敏感性分别为95.1%(39/41)、97.3%(36/37),阳性预测值分别为84.8%(39/46)、90.2%(37/41),假阴性率分别为4.9%(2/41)、2.6%(1/37)。结论:CT、MRI能较准确地反映喉及下咽癌喉外侵犯范围,这对于临床治疗有很大帮助。
Objective: To investigate the value of CT and MRI in the diagnosis of laryngeal carcinoma and hypopharyngeal carcinoma. Methods: The CT and MRI findings of throat and throat cancer in 33 cases of throat and hypopharyngeal carcinoma were retrospectively analyzed. The extent of throat invasion was judged according to CT and MRI signs. The results were compared with those of surgical pathology. Results: The sensitivity of CT and MRI in assessing the invasion of tumor throat or external structure were 95.1% (39/41) and 97.3% (36/37), respectively. The positive predictive value was 84.8% (39/46) and 90.2% 37/41). The false negative rates were 4.9% (2/41) and 2.6% (1/37) respectively. Conclusion: CT and MRI can accurately reflect the extent of larynx and hypopharyngeal carcinoma outside the scope of invasion, which is of great help for clinical treatment.
