本文报道41例胸腰椎损伤的X线和CT检查的对比评价结果,发现X线平片对椎间盘损伤、中柱损伤和椎管受压的诊断率只有CT的73%、88%和76%.对脊椎后柱结构损伤的诊断率只有CT的58～92%,但CT对中柱损伤的力学类型不易鉴别.通过对X线平片与CT的对比评价,作者指出,在CT片上测量椎体横径和矢径优于X线平片,而X线平片对椎弓根间距测量优于CT, This paper reports 41 cases of thoracolumbar injury by X-ray and CT examination of the comparative evaluation results and found that X-ray film on the disc injury, the column injury and spinal canal compression rate of CT diagnosis of only 73%, 88% and 76%. The diagnosis rate of spinal posterior column structural damage is only 58-92% of CT, but CT is not easy to identify the type of mechanical injury.According to the comparative evaluation of X-ray and CT, the author points out that measuring vertebral body Transverse diameter and radius of curvature is superior to X-ray, and X-ray film is superior to the CT measurement of pedicle spacing,
