目的 探讨X线片与CT扫描在胸腰 段脊柱骨折诊断中的差异及应用价值。方 法 选取2013年1月-2015年1月在我院诊 断治疗的胸腰段脊柱骨折患者82例为研 究对象，入院后均进行X线检查及CT扫描 检查，并以手术证实结果为标准，比较 两个检查手段在胸腰段脊柱骨折诊断方面 的影像学差异以及诊断符合率。结果 82 例患者经手术病理证实共有103个椎体骨 折，其中单个椎体骨折61例，多个椎体骨 折21例，主要损伤部位为T12-L2；以手术 证实结果为标准，X线片检查对胸腰段脊 柱骨折分型的综合符合率为54.9%，而CT 扫描检查为82.9%，差异具有统计学意义 (P<0.05)；这3种骨折类型的X线片、CT 扫描影像学特征具有一定的差异；X线片 检查对胸腰段脊柱骨折的诊断符合率为 53.7%，而CT扫描检查为87.8%，差异具有 统计学意义(P<0.05)。结论 在临床诊断 胸腰段脊柱骨折的过程中，与X线片检查 诊断相比较，CT扫描检查诊断的符合率更 高，提供的信息更多更可靠，它具有更好 的应用前景，值得临床进一步推广与应 用。

Objective To investigate the difference and application value of X ray and CT scan in the diagnosis of thoracolumbar spinal fracture. Methods 82 cases of thoracolumbar spinal fracture patients in our hospital were selected from January 2013 to January 2015. X line and CT scan were performed in all patients after admission. The results were confirmed by surgery, compared the diagnostic accuracy of the two methods in the diagnosis of thoracolumbar spinal fracture and the diagnostic accuracy. Results After surgery and pathology confirmed that 82 cases of patients with a total of 103 vertebral fractures, including a single vertebral fracture in 61 cases, multiple vertebral fractures in 21 cases, the main injury site was T12-L2. The results were confirmed by surgery. The comprehensive compliance rate of X-ray examination for thoracolumbar spinal fracture classification was 54.9%, while the CT scan examination was 82.9%. The difference was statistically significant (P<0.05). There are some differences in the characteristics of X-ray and CT scan in the 3 types of fracture. The diagnostic accuracy of X-ray film was 53.7%, while the CT scan examination was 87.8%.There was statistical significance in the difference of diagnostic accuracy (P<0.05). Conclusion In the process of clinical diagnosis of thoracolumbar spinal fracture, compared with X-ray examination and diagnosis, CT scan is more accurate and reliable, it has a better application prospect, and it is worthy of further popularization and application.
