目的探讨单光子发射计算机断层摄像联合同机电子计算机X射线断层扫描技术（single photo emission computed tomography and computer tomography，SPECT/CT）图像融合对老年人骨质疏松性椎体骨折的诊断价值，并总结其特征性影像学表现。方法回顾性分析63例有磁共振成像（magnetic resonance imaging，MRI）检查禁忌，经随访证实骨质疏松性椎体骨折患者的临床及SPECT/CT图像融合资料，评价其影像诊断价值并总结其影像学特征。结果63例患者共检查435个椎体，确诊骨质疏松性椎体骨折183个。结合临床病史，SPECT/CT诊断急性期骨折89个，亚急性期骨折53个，其中隐匿性骨折16个；陈旧愈合骨折41个。急性期和亚急性期患者SPECT/CT表现为椎体内显像剂条带状或团状异常浓聚；其中椎体形态出现双凹变45个，楔形变43个，压缩变扁38个。隐匿性骨折表现为椎体内显像剂团状异常浓聚，但椎体形态结构无改变。陈旧愈合骨折表现椎体形态结构改变但无或较淡的显像剂浓聚。结论 SPECT/CT图像融合可准确诊断骨质疏松性椎体骨折，结合临床病史并依据其影像学特征可大致判断骨折时间。

ObjectiveTo explore the diagnostic value and to summarize the imaging features of bone SPECT/CT in patients with osteoporotic vertebral fracture.Methods To explore the diagnostic value and to summarize the imaging features of bone SPECT/CT in patients with osteoporotic vertebral fracture.Results Of 435 vertebrae evaluated, 183 osteoporotic vertebral fractures were detected. Combined with the clinical history, the fractures were acute(89), subacute(53), and chronic(41)on SPECT/CT. 16 of the 53 subacute fractures were occult. Acute and sub-acute fractures showed clumped or stripes of bone uptake in the vertebral bodies. The fractures were biconcave(45), wedge-shaped(43), or completely collapsed (38). The occult fractures showed clumped bone uptake without morphological change. There was slight or no abnormal bone uptake with morphological change in the chronic fractures.Conclusion SPECT/CT image fusion allows accurate diagnosis and estimation of the age of osteoporotic vertebral fracture.
