摘　　要：目的探讨骶骨衰竭骨折的^(18)F-FDG PET/CT显像特点。方法回顾性分析接受^(18)F-FDG PET/CT检查、诊断为衰竭骨折的8例患者的资料。结果 8例患者均发现骶骨有不同程度的异常放射性摄取增高,最大标准摄取值(SUVmax)为2.7~7.2。病变位于骶骨左侧翼4例、双侧骶骨翼及岬部2例、双侧骶骨翼1例、骶骨左侧翼及岬部1例;8例发生骶骨翼的纵行骨折,6例位于S1~2椎体,2例累及S3椎体,3例发生骶骨岬部的横行骨折,2例位于S2椎体,1例位于S3椎体;骶骨骨质密度增高5例、密度未见改变3例。结论骶骨衰竭骨折的^(18)F-FDG PET/CT显像有一定特点。Objective To explore the 18F-FDG PET/CT features of sacral insufficiency fracture. Methods 18F-FDG PET/CT imaging and clinical data of 8 patients with sacral insufficiency fracture were retrospectively analyzed. Results All 8 patients had different degrees of radioactivity uptake in sacra with the maximum standardized uptake value （SUVmax）from 2.7 to 7.2. Four patients had lesions in their left sacra, 2 in the bilateral sacral wings and sacral promontories, 1 in the bilateral sacral wings, and 1 in the left sacral wing and sacral promontory. There were 8 patients of longitudinal fractures in sacral wings, which of 6 patients involving S1-2 and 2 patients involving S3. Three patients had transverse fractures in sacral promontories, with 2 located at S2 and 1 at S3. The sacral bone density increased in 5 cases, and the density was not changed in 3 cases. Conclusion Sacral insufficiency fracture had specific 18F-FDG PET/CT characteristics.
