摘　　要：目的探讨螺旋CT三维重建检查术、胸部正位片+胸部透视检查术两种方法分别在诊断小儿呼吸道异物中的价值。方法 300例疑诊气管、支气管异物的患儿行螺旋CT三维重建及常规胸片、胸透检查,与手术及治疗结果对照。结果①螺旋CT三维重建:诊断异物244例,支气管镜检发现异物238例,6例未见异物;诊断肺部感染56例,其中14例行支气管镜检均未见异物,42例行保守治疗,症状均好转。其诊断灵敏度100%,特异度90.3%,约登指数0.903;②胸部正位片+胸部透视检查:诊断异物可能180例,经手术及治疗确诊异物164例,无异物16例;诊断肺部感染120例,经手术及治疗发现异物74例,无异物46例。其诊断灵敏度68.9%,特异度74.2%,约登指数0.431。结论螺旋CT三维重建对于支气管异物的诊断具有重要价值,其极高的灵敏度使其在诊断过程中可以作为是否行支气管镜检术的决定依据。Objective To evaluate the value of multi-slice CT（MSCT） three-dimensional reconstruction and Chest X-ray in the differential diagnosis of pediatric tracheobronchial foreign body. Methods 300 cases of suspected tra- cheo-bronchial foreign bodies were reviewed to evaluate the diagnostic value of MSCT three-dimensional reconstruc- tion and Chest X-ray. Results Sensitivity and specificity of MSCT three-dimensional reconstructiong were 100% and 90.3%, with its Youden index at 0. 903. However, sensitivity and specificity of normal Chest X-ray were 68.9% and 74.2%, with the Youden index at 0. 431. Conclusion MSCT three-dimensional reconstruction can im- prove the accuracy of diagnosis of tracheobronchial foreign body in children.
