摘　　要：目的通过分析全身骨显像时骶椎的放射性分布情况,探讨骶椎放射性分布浓聚及稀疏时的临床诊断。方法收集212例全身骨显像未见明确骨转移灶的病例,对这些病例的骶椎的放射性分布按年龄、性别进行分组对比,分别统计每个年龄段骶椎的放射性分布情况。结果骶椎放射性分布正常占57.6%,放射性分布略稀疏占31.1%,放射性分布略浓聚占11.3%。男女患者70岁以上骶椎放射性分布正常的比率明显降低,男/女患者70岁以上骶椎放射性分布稀疏的比率明显增高,女性70岁以上年龄段骶椎放射性分布浓聚比率明显高于男性。结论男性患者与女性患者出现骶椎放射性分布情况相近,性别影响因素较小。70岁以上老年人由于骨质疏松的存在,导致骶椎放射性分布略稀疏,而且骨质疏松性骶椎隐性骨折,常导致骶椎放射性分布略浓聚。Objective To analyze the radiogenic distribution in the sacrum in whole-body bone scanning. Methods A total of 212 patients receiving whole-body bone scanning without any explicit bone metastases were divided into different age and gender groups. The radioactive distribution in the sacrum in whole-body bone scanning was analyzed statistically. Results Of these cases, 31.1% presented with thin radioactive distribution in the sacrum and 11.3% exhibited increased radioactive distribution. Normal radioactive distribution in the sacrum was found in 57.6% of the cases. In both male and female elderly patients （〉70 years）, the rate of normal radioactive distribution in the sacrum was obviously reduced with increased rate of thin radioactive distribution. The female elderly patients showed higher rate of increased radioactive distribution in the sacrum than male elderly patients. Conclusions The radioactive distribution in the sacrum is similar between female and male patients. Elderly male patients over 70 years have generally thin radioactive distribution in the sacrum due to the presence of osteoporosis, which is also associated with latent fracture of the sacrum to result in increased radioactive＇distribution in the sacrum in whole-body bone scanning.
