目的：探讨ＣＴ对胸部创伤的诊断价值。方法：对照分析３５例胸部创伤的Ｘ线平片及ＣＴ表现；ＣＴ扫描均采用骨算法重建，拍照时采用两种窗位拍摄。结果：胸廓骨折Ｘ线平片检出２７例，ＣＴ检出２１例，差异无显著性（Ｐ＞０．０５）；胸膜外伤ＣＴ检查２２例，Ｘ线平片检出１３例；肺部损伤ＣＴ检查３５例，Ｘ线平片检出１５例；差异均有显著性（Ｐ＜０．０１～Ｐ＜０．００５）。结论：胸部Ｘ线平片仍然是胸部创伤首选检查方法；ＣＴ能明确创伤病变的部位、性质，对肺损伤及胸膜外伤的诊断价值明显优于Ｘ线平片。
Objective: To investigate the diagnostic value of CT in chest trauma. Methods: Thirty-five cases of thoracic trauma were examined by X-ray and CT. CT scan was reconstructed by bone algorithm. Results: Twenty-seven cases were detected by X-ray and 21 cases by CT. There was no significant difference between the two groups (P> 0.05). CT was detected in 22 cases of pleural trauma and X-ray was detected in 13 cases. 35 cases were detected by CT and 15 cases were detected by X-ray. The difference was significant (P <0.01 ~ P <0.005). Conclusion: Chest radiographs are still the preferred method of chest trauma. CT can clearly identify the location and nature of traumatic lesions and the diagnostic value of lung injury and pleural trauma significantly better than plain radiographs.
