摘　　要：目的研究CT、MRI和SPECT对鼻咽癌颅底骨侵犯的检测能力。方法对56例鼻咽癌初治患者进行CT、MRI和SPECT检查。结果CT、MRI和SPECT颅底骨侵犯阳性检出率分别为25.0%(14/56)、44.6%(26/56)和28.6%(16/56),差异有统计学意义(χ2=6.593,P=0.037);破坏的部位以斜坡最多见。结论MRI对鼻咽癌颅底骨侵犯的检测能力优于CT和SPECT。Objective To investigate the detection ability of computerized tomography（CT）,versus magnetic resonance imaging （MRI） and Single photon emission computed tomography （SPECT） in skull base invasion in nasopharyngeal carcinoma （NPC）. Methods Fifty-six patients of NPC were examined by plain CT ,MRI and SPECT. Results The overall positive rates of skull base invasion detected by CT ,MRI and SPECT were 25.0% （14/56）,44.6% （26/56）Vs 28.6%（16/56）respectively （ X^2=6.593,P=0.037）.The most common site of bony invasion was basilar clivus. Conclusion The detection ability of MRI in skull base invasion in NPC is superior to that of CT and SPECT.
