目的探讨老年人脊椎骨折特点及多层螺旋CT后处理技术在脊柱骨折中的应用价值。方法对43例老年脊椎骨折患者椎体进行容积重建(VR)，最大密度投影(MIP)及多平面重建(MPR)，并结合0.625 mm薄层轴位图像观察。结果多层螺旋CT重建成像技术能清晰、直观显示骨折部位、椎体骨折内部情况及周围空间结构关系。结论老年人因骨质疏松极易发生脊椎骨折，多层螺旋CT重建技术可对脊椎骨折诊断及治疗提供重要信息。“,”Objective To investigate the characteristics of senile vertebral fractures and the application value of multi-slice spiral CT technique in fracture of spine.Methods The volume reconstruction of 43 cases of elderly patients with spinal fracture(VR),the maximum intensity projection(MIP) and multiplanar reconstruction(MPR), combined with 0.625mm thin axial image observation. Results Multislice spiral CT imaging can clearly display the fracture site,inside and around the spatial structure of cone fracture. Conclusion Old people with osteoporosis prone spine fractures, multislice spiral CT technology can provide important information for the diagnosis and treatment of vertebral fractures.
