摘要
目的:研究CT及MRI对鼻咽癌颅底骨侵犯的检测能力及诊断价值。方法:60例鼻咽癌初治患者,于放射治疗前同期进行鼻咽颅底连续横断位CT扫描及FSE轴、冠、矢状位T1WI和轴位T2WIMRI检查,对两者检测结果进行比较。结果:CT、MRI对颅底骨侵犯的阳性检出率在全部患者中为16.7%、53.3%。经检验,P<0.001,有显著性意义。破坏的部位均以斜坡最多见。结论:MRI对鼻咽癌颅底骨侵犯的检测能力优于CT。
Purpose:To investigate the detection ability of CT and MRI in skull base invasion in nasopharyngeal carcinoma. Methods:Sixty patients with nasopharyngeal carcinoma were examined by plain CT scan at axial sections and MRI of T_(1)WI at axial , coronal and sagittal sections and T_(2)WI at axial sections fast spin echo (FSE). Results:The overall positive rates of skull base invasion detected by CT and MRI were 16.7% and 53.3%(χ~2 Test,P<0.001). The most common site of bony invasion was basilar clivus. Conclusions:The detection ability of MRI in skull base invasion in nasopharyngeal carcinoma is superior to that of CT.
