核素骨显像在肿瘤患者随诊中的应用

Application of radionuclide bone imaging in follow-up patients with tumor

目的 :评价核素骨显像在恶性肿瘤患者随诊中的意义。方法 :1 0 0例恶性肿瘤患者行 2 75次常规99mTc 亚甲基二磷酸盐 (MDP)全身骨显像。观察分析全身骨骼放射性分布情况。结果 :首次骨显像诊断骨转移瘤 1 8例 ,第 2次骨显像发现骨转移瘤 1 4例 ,第 3次及第 4次骨显像分别诊断骨转移瘤 1例与 2例。首次骨显像到发生骨转移的时间为 2～ 2 4个月 ,平均 7个月。结论 :定期复查骨显像能及时发现骨转移瘤 ,有利于制定治疗方案及评估疗效。

Objective:To evaluate the significance of radionuclide bone imaging in follow up patients with malignant tumor.Methods:100 patients with malignant tumor underwent a total of 275 times of ( 99m Tc methylene diphosphonate, 99m Tc MDP) whole body scintigraphic imaging to observe and analyze radiodistribution of whole body.Results:18 patients were defined as metastatic osteoma at the first bone imaging. 14 patients, 1 patient and 2 patients were diagnosed at the second, third and fourth whole body scintigraphic imaging, respectively.It was about 2 to 24 months from first bone imaging to bone metastatic occurring, and the mean interval was 7 months.Conclusion:Metastatic osteoma can be found in time and much earlier with periodic bone imaging. It's helpful to work out therapeutic methods and assess the effect of treatment.
