Application Value of 3-D reconstruction with Spiral CT in Lumbar Trauma

摘要: 目的:探讨螺旋CT三维成像在腰椎创伤性骨折诊断中的价值。方法:选取腰椎创伤性骨折患者76例,经CT轴位平扫(2DCT)后进行三维重建(3-DCT)即表面遮盖(SSD)及多平面重建(MPR),将其图像资料进行比较。结果:3-DCT能立体、直观显示腰椎创伤性骨折的部位、类型、三柱结构、椎管狭窄及脊髓受压等情况。结论:3-DCT作为2DCT的重要补充,对腰椎创伤性骨折临床治疗方案的选择及预后判断有指导意义;SSD及MPR既有良好形态学又有密度层次的图像,可协助三维显示椎间盘碎裂、突出和膨出的范围。Abstract: Objective To investigate the application value of 3D reconstruction with spiral CT in lumbar trauma. Methods: 76 cases with Lumbar trauma were examined by CT axial scan,the images of each were done by 3D reconstruction (SSD,MPR) and then compared with routine 2DCT.Result: The location and types of Lumbar fracture,Lumbar three columns structure,narrowing of Lumbar canal,the nerve roots and spinal cord to be compressed were revealed accurately and stereoscopically by 3D imaging.Conclusion: 3D reconstruction of spiral CT is an important complement of trans-axial images.It is helpful to select reasonable treatment plan and judge curative effect.It can help to show vertebra trauma and display intervertebral disk trauma intuitionistically.
