摘　　要：目的分析缺血性椎体压缩骨折的影像变化及特点。方法随访11例初诊为骨质疏松性压缩骨折,复诊确定为缺血性椎体压缩骨折的病例。复诊时采用不同体位行X线摄影,并于透视下观察病变椎体在不同体位下的形态和变化特点,其中8例并同时行螺旋CT扫描。对初诊及复诊的X线及CT图像进行对比观测分析。结果11例病例的影像动态变化特点均表现为进行性椎体塌陷及后凸畸形;萎陷的椎体呈扁平状或薄骨板样(8例)、鱼椎状(3例),萎陷的椎体内均可见真空裂隙征。结论缺血性椎体压缩骨折的影像学具有一定特征性。Objective To analyse the imaging variety and characteristics of vertebral body with ischemic compression fractures. Methods 11 patients whose initial diagnosis was osteoporotic vertebral compressed fractures while the final diagnosis was ischemic vertebral compression fractures were followed - up, During their subsequent visit 11 cases were undergone radiographic examination and the morphologic and the characteristics of variety of the vertebral body with compressed fractures were observed under X - ray fluoroscopy in the different position. 8 cases were undergone spiral CT scan. The all imaging data of 11 cases were analysed. Results The dynamic imaging findings of the compressed vertebral body in 11 cases were progressive vertebral collapse and kyphosis . The collapsed vertebral bodies were flat in morphology in 8 cases,biconcave in 3 cases. The vacuum cleft was present in all collapsed vertebral bodies. Conclusion The imaging features of ischemic vertebral compressed fractures are of certain characteristic.
