摘　　要：目的：比较鼻咽癌侵犯颅底时CT与MRI在显示侵犯程度上的差异。结果：30例鼻咽癌中CT显示骨质破坏12例。MRI显示骨质破坏15例。CT显示海绵窦侵犯2例。MRI显示海绵窦侵犯5例。结论：CT与MRI检查显示颅底侵犯情况效果基本相仿。如果肿瘤侵润骨组织尚未发生骨皮质破坏时，MRI优于CT。MRI在显示病变与颅底、海绵窦、脑、脑膜的关系方面优于CT。TO investigate the difference of CT and MRI in displaying carcinoma of nasopharynx which invading the base of skull. Results: 12 cases of nasdpharynx out of 30 cases were displayed by CT. with a disruption of bo skull bone. while 15 out of 30 were displayed by MRI. 2 cases with cavernous sinus invaded were displayed by CT,while 5 cases were displayed by MRI. Conclusions: CT and MRI have a sinwilar effect in displaying violation of base of skull. but MRI is prior to CT if bone displying the relation ship between the lisease and the base of skull. cavernous sinus. encephalon and meninge.
