目的　对肺小细胞癌的患者在确诊早期进行核素骨显像 ,以观察其骨转移的发生率。方法　对确诊为肺小细胞癌的患者 ,4天～ 3个月内用SPECT进行全身骨显像 ,用计算机处理成前后位和后前位两幅全身骨骼图像。显像剂为99mTc -MDP。结果　 38例肺小细胞癌患者中 ,有 9例已发生多发性骨转移 ,总转移率为 2 3 1%。其中 ,男 7例 ,占男性患者的 2 4 1% ,女 2例 ,占女性患者的2 2 2 %。结论　一旦确诊为肺小细胞癌患者 ,做核素全身显骨像检查 ,对病变分期、治疗方案选择及其预后具有重要的临床参考意义。 Objective To detect radionuclide bone scintigraphy in early diagnosis of small cell lung cancer in order to observe the incidence of bone metastases. Methods Patients diagnosed with small cell lung cancer within 4 days to 3 months with SPECT whole body bone imaging, computerized into the anterior and posterior and posterior two full body images. The imaging agent is 99mTc-MDP. Results Of the 38 patients with small cell lung cancer, 9 had multiple bone metastases with a total rate of 23.1%. Among them, 7 males, accounting for 24.1% of males, 2 females, accounting for 22.2% of females. Conclusion Once the diagnosis of small cell lung cancer patients, to do nuclide whole body bone imaging examination, the lesion staging, treatment options and prognosis of important clinical significance.
