摘　　要：目的对比分析多排CT在诊断小儿支气管炎内异物的诊断价值。方法对我院进行治疗的经纤支镜确诊为支气管异物的患儿76例,分别对其进行X线检查及16排螺旋CT检查,对比观察两种检查方式的诊断准确性。结果 76例患儿左支气管、主支气管及右主支气管异物应用16排螺旋CT诊断符合率为100%,其中直接提示气管异物占88.1%,间接征象占11.9%;X线临床诊断符合率为85.5%,其中直接征象占18.4%,间接征象占81.6%。螺旋CT对左支气管、中段支气管、右主支气管异物及总的诊断符合率均明显高于X线诊断符合率,差异有统计学意义(P<0.05)。结论多排CT对小儿支气管内异物具有较高的临床应用价值。Objective Comparative analysis of the diagnosis value of multi slice CT in the diagnosis of foreign bodies in children with bronchiolitis.Methods 76 children who were confirmed by fiberbronchoscope in our hospital were chosen, X-ray examination and 16 slice spiral CT examination were performed respectively, diagnosis accuracy of two methods were compared.Results The accordance rate of 16 slice spiral CT in the diagnosis of middle left bronchus, bronchus and right main bronchus were 100%, The direct indication of tracheal foreign body accounted for 88.1%, The indirect signs accounted for 11.9%; Clinical X-ray diagnosis coincidence rate was 85.5%, The direct signs accounted for 18.4%, The indirect signs accounted for 81.6%.the diagnosis rates of spiral CT were obviously higher than the X-ray, The difference had statistically significant（P〈0.05）. Conclusion Multi slice CT has high value in the diagnosis of bronchial foreign bodies in children.
