【摘要】：目的探讨多层螺旋CT(MSCT)扫描及MPR矢状位重建图像技术在胸腰椎压缩骨折患者影像学诊断的应用价值。方法选取我院收治的胸腰椎压缩骨折患者96例为研究对象,均行X线、MSCT检查,比较两种方法诊断胸腰椎压缩骨折的灵敏度、特异度、准确度,并分析椎体骨折分布情况及不同类型胸腰椎压缩骨折的显示率,观察胸腰椎压缩骨折的MSCT影像特征。结果 96例患者骨折椎体114例,范围为T12-L5椎体,其中以T12-L1椎体最多(75.44%);MSCT诊断胸腰椎骨折的灵敏度75.00%、准确度73.96%明显高于X线检查60.00%、64.58%(P0.05),特异度比较无显著差异(P0.05);MPR重建中矢状位对胸腰椎压缩骨折的显示率90.91%较冠状位69.42%、横断面64.46%高(P0.05);MPR矢状位重建图像显示骨折整体,立体感强,能很好地显示椎管变形、椎管内碎骨片。结论 MSCT扫描及MPR矢状位重建图像技术对胸腰椎压缩骨折具有重要的诊断价值,值得在临床推广应用。
[Abstract]:Objective to evaluate the value of multislice spiral CT (MSCT) and MPR sagittal reconstruction in the diagnosis of thoracolumbar compression fracture. Methods Ninety-six patients with thoracolumbar compression fractures were selected as subjects. MSCT examination was performed in all patients. The sensitivity, specificity and accuracy of the two methods in the diagnosis of thoracolumbar compression fractures were compared. The distribution of vertebral body fractures and the display rate of different types of thoracolumbar compression fractures were analyzed, and the MSCT imaging features of thoracolumbar compression fractures were observed. Results there were 114 cases of fracture vertebral body in 96 patients with T12-L5 vertebral body. The sensitivity of T12-L1 in diagnosing thoracolumbar fractures was 75.00% (75.44%), and the accuracy of 73.96% was significantly higher than that of X-ray examination of 64.58% (P0.05). There was no significant difference in specificity (P0.05). The display rate of thoracolumbar compression fractures in sagittal position was 90.91% compared with that in coronal 69.42. 64.46% high (P0.05) MPR sagittal reconstruction images showed the fracture as a whole. Strong sense of three-dimensional, can well show deformation of the spinal canal, bone fragments in the spinal canal. Conclusion MSCT scan and MPR sagittal reconstruction are valuable in the diagnosis of thoracolumbar compression fracture.
