摘要
目的:评价螺旋CT扫描与多模式三维重建在腰椎间盘突出症(lumbar disc herniation,LDH)中的应用。方法:回顾性分析我院行CT检查,并经手术证实的腰椎间盘突出症87例,应用多平面重建(MPR)、表面遮盖显示(shaded surface dispinal,SSD)和仿真内镜(virtual endoscopy,VE)等软件显示病变。结果:腰椎间盘突出症以L4～5和L5～S1为好发部位,其CT表现主要为向后方或侧方突入椎管内前缘的软组织影、硬膜囊受压;多模式三维重建不仅能发现腰椎间盘突出、膨出,还能显示出椎体、附件及周围组织的病变。结论:CT多模式三维重建不仅对LDH的诊断具有重要价值,而且对椎体和附件及周围的病变有很高的诊断价值。
Objective：To evaluate the application of spiral CT scanning and multi-mode three-dimensional（3D） reconstruction in lumbar disc herniation（LDH）.Methods：87 patients with LDH detected by computed tomography（CT） and confirmed by operation in our hospital were retrospectively analyzed.The patients were performed several kinds of 3D reconstruction,including multiplanar reconstruction（MPR）,shaded surface display（SSD） and virtual endoscopy（VE） for revealing lesions.Results：In this group,L4～5 and L5～S1 were the predilection sites of LDH.The main CT manifestations were the soft tissue shadow backward or laterally protruded to the frontal edge of spinal canal and compressed dural sac.The multi-mode 3D reconstruction not only showed the protrusion and bulging of lumbar disc,but also revealed the diseases of vertebral body,accessories and adjacent tissues.Conclusion：The multi-mode 3D reconstruction of CT has important diagnostic value for diagnosing LDH and lesions of vertebra body,accessories and adjacent tissues.
