摘要
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 resonanceimaging,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.
