目的:观察鼻咽癌(NPC)骨转移的特点;与CT对比,分析颅底骨转移病灶检测的敏感性。方法:151例 NPC SPECT~(99m)Tc-MDP全身骨显像,其中 66例作头颅正侧位骨显像及CT 扫描。结果:151 例NPC骨显像阳性98例,占64.9％;其中颅底骨阳性显示者43例,占28.5％;66例与CT对比结果,骨显像检出颅底阳性26例,占39.4％;CT 检出16例,占24.2％。结论:核素骨显像对NPC骨转移病灶诊断具有较高敏感性,对颅底病灶检测敏感性高于CT。核素骨显像对NPC分期,选择治疗方案,预后评估具有重要价值。
Objective: To observe the characteristics of bone metastases of nasopharyngeal carcinoma (NPC) and compare with CT to analyze the sensitivity of detection of skull base metastases. Methods: 151 cases of SPECT ~ (99m) Tc-MDP bone scintigraphy were performed in 151 cases, including 66 cases of skull bone scintigraphy and CT scan. Results: 151 cases of NPC bone imaging positive in 98 cases, accounting for 64.9%; of which skull base was positive in 43 cases, accounting for 28.5%; 66 cases and CT contrast results, bone imaging positive skull base detected in 26 cases, accounting for 39.4 %; CT detected in 16 cases, accounting for 24.2%. Conclusion: Radionuclide bone imaging is highly sensitive to the diagnosis of NPC bone metastases, and is more sensitive to the detection of skull base lesions than CT. Radionuclide bone imaging for NPC staging, treatment options, prognostic evaluation of great value.
