摘要
目的通过分析鼻咽癌在纤维鼻咽镜下、CT和MRI的影像学表现,评价其诊断价值。方法回顾性分析经病理证实的82例鼻咽癌的CT和MRI的影像学检查资料作分期比较。结果鼻咽癌各期(T1,T2,T3,T4)CT和MRI方法的阳性检测率分别是42.7%和19.5%,13.4%和17%,24.4%和39%,19.5%和24.4%(<0.05);鼻咽癌颈部淋巴结转移各期(N0,N1,N2,N3)分别是51.2%和40.2%,18.3%和28.0%(<0.05);19.5%和20.7%,11.0%和11.0%(>0.05)。结论纤维鼻咽镜能清楚显示鼻咽腔内病变部位及范围,并能在直视下进行活检。MRI在鼻咽癌的诊断和T分期及N0、N1中优于CT。
Objective To evaluate the diagnostic values of CT and MRI by analyzing the imaging behavior of human nasopharyngeal carcinoma.Methods 82 cases of patients with nasopharyngeal carcinoma,confirmed by nasopharygo-fiberscope and pathological observation,were analyzed retrospectively using CT and MRI.Results According to 2008 staging system of China,the positive detection rates of nasopharyngeal carcinoma（T1,T2,T3,T4）by CT and MRI methods were 42.7% and 19.5%,13.4% and 17%,24.4% and 39%,19.5% and 24.4%（ P〈0.05）respectively;the positive detection rates for nasopharyngeal carcinoma with cervical lymph node metastasis（N0,N1,N2,N3）by CT and MRI were 51.2% and 40.2%,18.3% and 28.0%（P〉0.05）;19.5% and 20.7%,11.0% and 11.0 %（ 0.05）respectively.Conclusion Nasopharygo-fiberscope can show clearly the location and extent of lesions,and biopsy can be carried out under direct vision.MRI is superior to CT in the diagnosis of nasopharyngeal carcinoma.
