摘　　要：目的:探讨儿童支气管异物的多层螺旋CT诊断价值。方法:对33例儿童气道异物进行三维重建,8例同时进行低毫安(ma)量的胸部CT扫描,回顾分析其影像学表现。结果:气管内5例,左主支气管13例,右主支气管8例;中间主支气管3例,左、右下支气管异物各2例。以花生米、瓜子类为主。CT征象包括:异物直接显示,阻塞性肺气肿。结论:多层螺旋CT能清晰显示气管支气管树,能直接而准确定位异物为支气管异物提供一种新的更准确的术前诊断途径。Objective：To evaluate the applied value of multi-slice spiral （MSCT） in diagnosis of bronchial foreign bodies in children. Methods： Three dimension of foreign body in the aiyway was reconstructecl in 33 cases using MSCT. All of them were diagnosed to have FB and confirmed with fiberoptic bronchoscopy,low-tube-current MDCT was performed in 8 patients. Results： Among the 33 patients, the foreign bodies were in the trachea in five patients,in the right main bronchus in eight patients, in the bronchus intermedius in three patients, in the left main bronchus in thirteen patients, 2 in the right inferior lobar branchus and 2 in left inferior lobar branches. FB mainly was peanut and melon seeds. CT features were as follows： complete or partial obstruction of bronchial lumen in cases of direct display of FB and obstructire pulmonary emphysema. Conclusion： MDCT scanning can clearly exhibit the trachial and bronchial tree, correctly localize the FB and provides a noninvasive and sensitive diagnostic technique in bronchial foreign body aspiration.
