[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。
[Objective] To evaluate the value of CT and MRI in the detection and diagnosis of skull base bone in nasopharyngeal carcinoma. [Method] 128 cases of nasopharyngeal carcinoma newly diagnosed by pathology were examined by CT and MRI. [Results] The detection rates of CT and MRI on the skull base bone invasion were 19.53% (25/128) and 49.22% (63/128) respectively (P <0.05). Among them, 6 cases (24.00%) were detected by single-site CT, 19 cases (76.00%) were multi-site invasion, 18 cases (28.57%) were detected by MRI and 45 cases (71.43%) were multi-site. [Conclusion] MRI is superior to CT in the detection of skull base bone invasion of nasopharyngeal carcinoma. MRI is more sensitive than CT in early stage of bone marrow invasion of nasopharyngeal carcinoma. It is helpful for the accurate staging of nasopharyngeal carcinoma and the rational development of clinical treatment plan .
