核素骨显像在鼻咽癌患者放疗后疑有骨转移时的应用

Clinical assessment of bone scanning in 78 patients with nasopharyngeal carcinoma after radiotheraphy

目的:评价全身骨放射性核素显像对鼻咽癌患者放疗后疑骨转移的临床价值。方法:78例鼻咽癌 患者放疗后行全身骨放射性核素显像,显像剂为99m锝 亚甲基二膦酸盐(99mTc MDP)。结果:78例鼻咽癌患者放 疗后核素骨显像示骨转移47例,其中鳞状细胞癌46例,未分化癌1例。结论:全身骨放射性核素显像对鼻咽癌 患者放疗后的监测及治疗方案的选择和预后均有重要的临床参考价值。

Objective:It is an evaluation of radionuclide bone scanning in detecting bone metastasis in the patients with nasopharyngeal carcinoma after radiotheraphy.Method:The bone scanning was performed in 78 patients with nasopharyngeal carcinoma after radiotheraphy.Result:Bone metastasis were detected in 47 patients out of 78, including 46 squamous cell carcinoma and 1 undifferentiated carcinoma.Conclusion:Radionuclide bone imaging is useful for diagnosing,treating and prognosing of nasopharyngeal narcinoma.
