目的探讨多层螺旋CT及X线片 对于肺挫裂伤的诊断价值。方法 对31 例临床怀疑肺挫裂伤的伤者进行临床随 访、多层螺旋CT扫描、X线平片检查。并 对多层螺旋CT扫描结果及X线平片检查结 果进行分析。结果 多层螺旋CT显示肺挫 伤26例，裂伤5例。X线平片漏诊6例、误 诊2例。结论 多层螺旋CT能够明确诊断 肺挫裂伤的部位、范围、性质、程度、 合并症及进行鉴别诊断，为临床提供较X 线平片更多的诊断信息、治疗依据。多 层螺旋CT是目前诊断肺挫裂伤的最重要 的检查方法。

Objective To explore diagnostic value of Multi-slice spiral CT (MSCT) and X-ray film on the pulmonary contusion and laceration. Methods MSCT scan and X-ray imaging were performed in 31 cases with suspected pulmonary contusion and laceration after clinical follow-up. The two sets of data were comparatively analysed. Results MSCT diagnosed 26 cases of pulmonary contusion, 5cases of laceration. X-ray missed 6 cases and misdiagnosed 2 cases. Conclusion The MSCT scan technology could definitely display the location, extent, nature, degree, complications and differential diagnosis of pulmonary contusion and laceration, providing more valuable diagnostic information and therapeutic basis than X-ray film. So MSCT is the most important method of the diagnosis of pulmonary laceration and contusion.
