目的 分析骨转移癌全身骨显像的特点 ,提高核素骨显像的诊断水平。方法 63 8例恶性肿瘤患者行99TCm-MDP全身骨显像并分析。结果 ①恶性肿瘤患者中有 67.9%发现骨转移 ,病灶分布分别为脊柱 3 4%、肋骨3 0 %、骨盆 18%、四肢骨 10 %、头颅 3 .3 %、胸骨锁骨 2 .4%和肩胛骨 2 .3 %。②绝大部分骨转移病灶为局限性放射性分布异常浓聚 ,减低仅占 0 .8%。骨转移以多灶为常见 ,单灶仅 10 .4%。③与X线检查对比 ,多数患者全身骨显像较X线片发现了数目更多和范围更广的病灶 ;少数患者骨转移灶X线片表现出明显的骨质破环 ,而骨显像上无明显的放射性分布异常。④患者主诉的 3 2 8处骨痛 ,骨显像发现为骨转移灶达 64 .9% ,另有 2 71个骨转移灶无明显骨痛。结论 ①骨转移癌的好发部位依次为脊柱、肋骨、骨盆、四肢骨、头颅、胸锁骨和肩胛骨。②全身骨显像对骨转移癌灶的探测灵敏度明显高于X线检查。与X线检查相互配合 ,可提高诊断的准确性。
Objective To analyze the characteristics of whole body bone imaging of bone metastases and to improve the diagnostic value of radionuclide bone imaging. Methods Sixty-three patients with malignant tumor underwent 99TCm-MDP whole body bone imaging and analyzed. Results ① 67.9% of patients with malignant tumors were found to have bone metastases. The lesions were 34% of the spine, 30% of the ribs, 18% of the pelvis, 10% of the extremities, 3.3% of the skull, 2.4% of the supraclavicular clavicle and the scapula twenty three %. ② The vast majority of bone metastases localized abnormal distribution of radioactive concentration, reducing only 0.8%. Bone metastases to multifocal as a single, only 10.4% single. ③ Compared with X-ray examination, the majority of patients with whole body bone imaging found more and more extensive lesions than X-ray films. In a few patients, bone metastases X-ray showed obvious broken bone, while bone imaging There is no obvious abnormal distribution of radioactivity. ④ In 32 2 cases of patients complained of bone pain, 64% of bone metastases were found in bone scintigraphy, and 2 71 had no obvious bone pain in bone metastases. Conclusions ① The predilection sites of bone metastases are spine, rib, pelvis, limbs, skull, thoracic clavicle and scapula. ② The whole body bone imaging detection of bone metastases foci sensitivity was significantly higher than the X-ray examination. Combined with X-ray examination can improve the diagnostic accuracy.
