三维CT重建在骨关节损伤及椎管狭窄诊断与治疗中的应用

Application of three dimensional CT reconstruction in the diagnosis and treatment of bone and joint injury and spinal stenosis

目的 :探讨三维CT重建在骨关节损伤及椎管狭窄中的作用。方法 :4 0例骨关节损伤及椎管狭窄患者均行X线片、CT平扫及三维CT重建检查 ,比较以上三种检查方法 ,评估各自的诊断价值。结果 :X线片对移位明显的骨折显示较好 ,但易造成漏诊或诊断不确定 ,对某些特殊部位的骨折不能较好显示 ;CT平扫可以较好显示骨折部位 ,但需要阅片者有丰富的临床经验并熟知局部解剖结构 ,否则 ,易造成诊断不全面。结论 :三维CT重建对制定详细的治疗方案可提供正确指导 。

Objective To explore the application of three dimensional(3D) CT reconstruction(3D CT R) in spinal stenosis and injury of the bone and joint. Methods Forty cases were examined with the X ray film, CT scan and 3D CT R. To evaluate their diagnostic value, the images of the three methods were compared. Results X ray films could show a visible shift of fracture pieces, but we were sometimes incapable of diagnosing fractures accurately from X ray and, therefore, we couldn't diagnose fractures located at a special position; the CT scan could show the fractured place with a better result, but it required that doctors should have enough clinic experience, and should be familiar with local anatomy to avoid possible misdiagnosis.Conclusion 3D CT R could be used in formulating a particular treatment scheme, and is an ideal examination method.
