螺旋CT对腰椎椎弓崩裂的诊断价值

Application of spirl CT in diagnosing lumbar spondyloschisis

目的探讨多层螺旋CT(MSCT)多平面重建在腰椎崩裂中的临床价值。资料与方法分析18例腰椎崩裂的轴位及多平面重建CT表现。结果多平面重建(MPR)矢状面图像和轴位对18例31处椎弓崩裂均显示良好,轴位对裂隙骨赘、骨痂、纤维组织增生,椎间盘病变等征象显示清晰,正中矢状面重建对椎体滑脱,椎体撕裂或骨赘后突显示良好。结论MSCT的轴位及多平面重建(MPR)对腰椎椎弓崩裂及其所引起的相关改变具有良好的显示效果,有利于临床制定手术方案。

Objective ： To evaluate multiplanarre construction（MPR） with spiral CT in the diagnosis of lumbar spondyloschisis. Methods： CT findings on axial,multiplanar images inl8 cases with lumbar spondyloschisis were analyzed. Results： MPR together with axial images could well display the entire picture of spondyloschisis and spinalcanal. Conclusion： Spiral CT together with MPR plays an important role in detecting spondyloschisis. A combination of axial images with MPR prorides vahable diagnostic and anatomic information helpful for the clinician to adopt optimal management.
