Review of abdominal CT scans for evaluation of blunt abdominal trauma yielded 35 cases of pneumothorax, 10 of which had not been diagnosed before CT by clinical examination or plain radiographs. Of the 10 cases initially diagnosed on CT, seven required tube thoracostomy for treatment of the pneumothorax. CT detection of pneumothorax is especially important if mechanical assisted ventilation or general anesthesia is used. Demonstration of pneumothorax requires viewing CT scans of the upper abdomen (lower thorax) at lung windows in addition to the usual soft-tissue windows.
回顾腹部CT扫描以评估钝性腹部创伤，发现35例气胸病例，其中10例在CT检查前通过临床检查或平片未被诊断出来。在最初通过CT诊断出的10例病例中，有7例需要进行胸腔闭式引流术来治疗气胸。如果使用机械辅助通气或全身麻醉，CT检测气胸尤为重要。除了常规的软组织窗位外，还需要在肺窗位观察上腹部（下胸部）的CT扫描来显示气胸。
