[摘要] 目的 探讨小儿气管与支气管异物诊断中放射影像技术的应用价值。方法 方便选取该院怀疑为气管及支气管异物的100例患儿(2015年1月—2018年12月)实施X线检查、多排螺旋计算机断层扫描(Computed tomography，CT)检查，比较X线、CT的诊断结果。结果 ①以纤维支气管镜诊断结果为参照，CT对气管及支气管异物的诊断灵敏度(95.77%)、特异度(96.55%)、准确率(96.00%)均高于X线(χ2=5.071、5.220、10.010，P<0.05)。②CT与纤维支气管镜诊断结果之间的一致性良好，Kappa值=0.814，而X线与纤维支气管镜诊断结果之间的一致性中等，Kappa值=0.632。结论 采用放射影像技术诊断儿童气管及支气管异物切实可行，尤其是螺旋CT，具有良好的诊断价值。

    [Abstract] Objective To study the application value of radiography in the diagnosis of foreign body in trachea and bronchus of children. Methods Convenient select a total of 100 children with trachea and bronchial foreign bodies in our hospital (January 2015 to December 2018) were selected and examined by X-ray and multi-slice spiral computed tomography (CT). The diagnostic results of X-ray and CT were compared. Results 1.According to the results of fiberoptic bronchoscopy ......
