摘　　要：目的探讨螺旋CT三维重建在脊柱病变中的应用。方法收集50例脊柱病变患者应用螺旋CT扫描脊柱获得原始轴位图像,然后再于3D中采用表面遮盖(SSD)、容积再现技术(VRT)和多平面重建(MPR)。结果螺旋CT三维重建图像能直观显示脊柱病变的全貌及"隐匿性"病变和细节病变的情况。结论16排螺旋CT曲面重建及VRT结合对病变诊断优于普通CT或X线平片,对治疗方案的选择及预后评估具有重要价值。Objective To investigate the three - dimensional reconstruction of spiral CT in spinal lesions of 50 patients with spinal collection, methods in patients with spinal application of spiral CT scanning was the original axial images,and then the use of 3 -D surface cover（SSD）, volume reproduction technology （VRT）and multi - MPR（MPR） o Results 3D reconstruction of spiral CT images showed that spinal lesions intuitive picture and the ＂occult＂lesions and lesions details of the situation. Conclusion 16 -slice spiral CT and surface reconstruction VRT with the diagnosis than the average CT or X - ray, the choice of treatment and prognostic evaluation of great value.
