目的探讨SPECT及CT对鼻咽癌颅底骨侵犯的检测能力。方法 2006年5月-2009年12月对159例经病理确诊的初治鼻咽癌患者行颅底SPECT断层显像,同期行CT检查,分别计算颅底受侵的阳性率。结果①159例鼻咽癌SPECT颅底断层阳性率46.5%(74/159),CT阳性率25.2%(40/159),SPECT检测敏感性高于CT(P<0.001)。②鼻咽癌伴颅神经损害SPECT检测敏感性高于CT(P=0.004)。结论 SPECT对鼻咽癌颅底骨侵犯的检测敏感性优于CT。
Objective To investigate the detection of nasal pharyngeal skull base invasion by SPECT and CT. Methods From May 2006 to December 2009, 159 patients with newly diagnosed nasopharyngeal carcinoma diagnosed by pathology underwent skull base SPECT scintigraphy and CT scan at the same period, and the positive rates of skull base invasion were calculated respectively. Results ① The positive rate of SPECT skull base tumor was 46.5% (74/159) and the positive rate of CT was 25.2% (40/159) in 159 cases of nasopharyngeal carcinoma. The sensitivity of SPECT was higher than that of CT (P <0.001). ② Sensitivity of SPECT to nasopharyngeal carcinoma with cranial nerve injury was higher than that of CT (P = 0.004). Conclusion SPECT is superior to CT in the detection of skull base bone invasion of nasopharyngeal carcinoma.
