摘要
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 study the value of computed tomography (CT) in the diagnosis of traumatic injuries in the bronchus and lung. Method A retrospective analysis was conducted of the CT and X-ray radiographic images of the bronchus and lung in 36 cases of traumatic injuries in the chest. Results Based on CT manifestations, the lung injuries of the 37 cases fell into 3 categories, namely mild, moderate and severe injuries. Of the 9 cases of mild lung injuries identified by CT, 5 failed to be detected by X-ray examination; in the 15 cases of moderate injuries, X-ray examination showed more confined areas of the injuries with lesser severity than CT did. In the rest 13 cases of severe injuries, only 9 were identified by X-ray. Bronchial injuries occurred in 3 case that were totally unidentifiable by X-ray and even routine CT scanning did not result in exact diagnoses. The injuries, however, were clearly demonstrated by thin-slice CT scan of the hila area after reconstruction of the images. Conclusion Chest X-ray is not sufficient for traumatic chest injury examination in the emergency room that necessitates CT scanning of the chest.
