Four children with occlut tracheobronchial foreign bodies were examined by computed tomography (CT) in order to establish whether CT is superior to plain radiography and xeroradiography in visualizing foreign bodies, as in vitro data suggest. In three patients the foreign body was localized by CT. CT is not recommended as a routine in the diagnosis of tracheobronchial foreign bodies but can be of value in the more difficult cases.
为了确定计算机断层扫描（CT）是否如体外数据所示，在显示气管支气管异物方面优于普通X线摄影和干板X线摄影，对4例气管支气管异物患儿进行了CT检查。3例患者的异物通过CT定位。不建议将CT作为气管支气管异物诊断的常规检查，但在较疑难病例中可能有价值。
