摘要
目的 :探讨CT在气管及支气管X线穿透性异物的表现及应用价值。方法 :回顾性分析 5 0例气管、支气管X线穿透性异物CT表现 ;所有异物均经临床纤维支气管镜取出证实。结果 :气管异物 4例 ,右主支气管异物 31例 ,左主支气管异物 15例 ;CT表现 :①异物本身 ;②局限性支气管阻塞、其下方支气管充气或轻度扩张 ;③纵隔移位及纵隔“双边” ;④胸部“双边” ;⑤肺气肿。结论 :CT扫描不仅能定位诊断 ,而且能直接显示异物本身 。
Objective:This article explored the value of CT expression and diagnosis of foreign body in the trachea and bronchus.Methods:The results of CT scanning of 50 cases of foreign body in the trachea and bronchus were retrospectively analysed,which were all verification by clinical and drawing out with fibrescope.Results:4 cases of foregign body in the trachea,31 cases of foreign body in the right major bronchus,15 cases of foreign body in the left major bronchus.CT expression:①the self of foreign body;②localized bronchus obstruction,the bronchus under it inflated air or slightly dilated;③mediastinal displacement and'two margins';④thorax'two margins';⑤emphysema;①and ② are the most imporant of them.Conclusion:CT scanning not only makes differential diagnosis but also shows directly the self of foreign body,which is superior to ordinary x ray examination.
