摘要
[目的]评价CT、MRI对鼻咽癌颅底骨质侵犯的检测及诊断价值。[方法]128例经病理证实的鼻咽癌初诊患者,均行CT与MRI检查。[结果]CT、MRI对颅底骨质侵犯的检出率分别是19.53%(25/128)和49.22%(63/128)(P<0.05)。其中CT检出单部位侵犯6例(24.00%),多部位侵犯19例(76.00%);MRI检出单部位侵犯18例(28.57%),多部位侵犯45例(71.43%)。[结论]MRI对鼻咽癌颅底骨质侵犯的检测优于CT,尤其在鼻咽癌早期骨髓侵犯方面MRI较CT敏感,其对鼻咽癌的准确分期及临床治疗方案的合理制定有帮助。
[Purpose] To investigate the detective ability of CT and MRI in skull base invasion of nasopharyngeal carcinoma （NPC）. [Methods] One hundred and twenty eight newly diagnosed patients with pathologically confirmed NPC were examined by both CT and MRI. [Results] The overall positive rate of skull base invasion detected by CT and MRI was 19.53%（25/128） and 49.22%（63/128）, with significant difference （P0.05）. There were 6 cases（24.00%）with single site involved and 19 cases（76.00%） with multi-sites involved in CT scans. There were 18 cases （28.57%）with single site involved and 45 cases（71.43%） with multi-sites involved in MRI. [Conclusion] The detective ability of MRI for skull base invasion in NPC is superior to that of CT. MRI imaging is more sensitive than CT especially in detecting NPC marrow invasion. It will benefit the staging of NPC and the clinical treatment strategy.
