67Ga scintigraphy was performed in 865 patients, and in 1078 examinations. 67Ga accumulation was evaluated retrospectively for asymmetric accumulation in the shoulders. Approximately 50% of patients showed no asymmetric distribution of 67Ga in the shoulders. About 40% of patients showed increased accumulation in the right side and about 10% of patients showed increased accumulation in the left side. A change of 67Ga distribution in the shoulder joints was recognized in about 30% of patients during the follow-up study. Reasons for asymmetric distribution of 67Ga in the shoulders were considered to be due to bone metastasis, changes of local blood flow, edema, irradiation, muscle atrophy after cerebral paralysis, and operation. 67Ga scintigraphy showed a broader range and more prominent accumulation in the soft tissues around the shoulder joint than 99mTc-MDP scintigraphy. The accumulation of 99mTc-MDP was recognized to be in the center of the region of 67Ga accumulation. 99mTc-MDP scintigraphy showed more prominently increased accumulation than 67Ga scintigraphy in patients with osseous lesions. Similar factors appeared to have had an influence on the abnormal accumulation of 67Ga and 99mTc-MDP around the shoulder joint.
对865例患者进行了67镓闪烁扫描，共进行了1078次检查。回顾性评估67镓在肩部的不对称积聚情况。约50%的患者肩部67镓无不对称分布。约40%的患者右侧积聚增加，约10%的患者左侧积聚增加。在随访研究中，约30%的患者肩关节67镓分布发生了变化。肩部67镓不对称分布的原因被认为是骨转移、局部血流变化、水肿、放疗、脑瘫后肌肉萎缩以及手术。与99m锝-亚甲基二膦酸盐闪烁扫描相比，67镓闪烁扫描显示肩关节周围软组织的范围更广且积聚更明显。99m锝-亚甲基二膦酸盐的积聚位于67镓积聚区域的中心。在有骨病变的患者中，99m锝-亚甲基二膦酸盐闪烁扫描显示积聚增加比67镓闪烁扫描更明显。类似因素似乎对肩关节周围67镓和99m锝-亚甲基二膦酸盐的异常积聚有影响。
