目的探讨CT在支气管肺外伤诊断中的作用。方法回顾性分析并比较37例胸部外伤患者支气管和肺组织损伤的X线胸片和CT表现。结果轻度肺组织损伤9例,5例X线胸片漏诊;中度15例,X线胸片显示病变较CT显示的范围小,程度轻;重度13例,4例X线胸片漏诊。支气管损伤3例,X线胸片均不能显示,常规CT扫描显示不肯定。结论胸部创伤的急诊检查,不能满足于X线胸片的粗略显示,还应该重视CT检查。 Objective To investigate the role of CT in the diagnosis of bronchial lung injury. Methods Retrospective analysis and comparison of radiographic and CT findings of bronchial and lung injury in 37 cases of thoracic trauma patients. Results There were 9 cases of mild lung injury and 5 cases of missed diagnosis of X-ray; 15 cases of moderate-grade X-ray. The range of X-ray showed that the lesion was lighter and lighter than the CT. Thirteen cases were severe and 4 cases were missed by X-ray. Bronchial injury in 3 cases, X-ray can not be displayed, conventional CT scan showed not sure. Conclusion The emergency examination of chest trauma can not be satisfied with the rough display of X-ray, but also should pay attention to CT examination.
