MSCT三维重建对脊柱侧弯的应用价值

目的:探讨16排螺旋CT三维重建对评价脊柱侧弯的意义及方法。方法:脊柱侧弯患者25例,在16排多层螺旋CT机上扫描后,行多平面重建(MPR)、表面遮盖重建(SSD)与容积再现(VRT)重建。评价不同的图像后处理技术的作用和优势。结果:25例脊柱侧弯患者的三维重建图像均能清晰显示椎体,椎弓根、椎管、椎旁组织及其脊髓的情况。测量椎弓根、椎体、椎管、椎体旋转角度等各种参数提供给临床。结论:螺旋CT多平面三维重建技术能准确提供脊柱侧弯患者脊柱、椎体、椎弓根、椎管等各种参数,对提高手术治疗的成功有很大的帮助。

MSCT Three-dimensional Reconstruction in Scoliosis Apply Value

Objective To evaluate the value of 16-slice helical CT and three-dimensional reconstruction postprocessing technique for diagnosis of scoliosis.Methods 25 cases of scoliosis were performed with multiple CT scan to be reconstructed by multiple planner reconstructed(MPR),surface shading display(SSD)and volume rendering(VRT),which were used to evaluale the value of the variousimages. Results The three-dimensional reconstruction images in 25 cases of scoliosis displayed a clear pedicle plane,at the sametime it also could distinguish the conditions of the vertebrae.spinal canal,spinal cord and the soft tissues aroundvertebrae.All the parameters relevant to pedicle,vertebrae,spinal canal and the rotation angles of vertebrae were labeled on the films,providing reliable reference for the physicians.Conclusion The three-dimensional reconstruction with spiral CT can offer、various parametess of the vertebrae concerning spine,spinal canal and the pedicle plane that will play very importantrole in the rectifying operation of scoliosis especially in the severe cases.
