目的：评价多层螺旋 CT 对小儿气管支气管异物的诊断价值。方法回顾性分析139例气管支气管异物的临床和 CT资料，后处理采用多平面重建(MPR)、曲面重建(CPR)、容积再现(VR)、最小密度投影(MinIP)、仿真内窥镜(VE)等技术，并与纤维支气管镜检查结果对照。结果139例中，气管异物13例，右侧支气管异物75例，左侧支气管异物48例，双侧3例。CT 正确诊断137例(98.6%)，漏诊2例(1.4%)；气管异物及右侧主支气管异物 CT 与纤维支气管镜检查结果有显著性差异(P <0.05)，但二者总体差异无统计学意义(P =0.340)。间接伴随征象：肺气肿74例，肺炎48例，肺不张22例，纵隔移位57例，间质性肺气肿4例，纵隔及皮下积气4例，支气管扩张2例，胸腔积液4例。结论多层螺旋 CT 及其后处理技术能准确直观地显示气管支气管异物及其继发征象，具有重要的临床应用价值。

Objective To evaluate the clinical value of multi-slice spiral CT in diagnosing tracheobronchial foreign bodies in chil-dren.Methods 139 patients with airway foreign body confirmed by bronchoscopy were examined with 128-slice spiral CT,and then the CT data was reconstructed by using multiple-planar reconstruction(MPR),curved planar reconstruction (CPR),volume render-ing(VR),minimum intensity projection(MinIP)and virtual endoscopy (VE).The CT results were compared with bronchofibersco-py findings.Results Among the 139 cases,the foreign bodies located at trachea in 13 cases,right bronchia in 75 cases,left bronchia in 48 cases,and bilateral bronchia in 3 cases.137 cases (98.6%)were correctly diagnosed,and 2 cases (1.4%)were missed on CT.Although the difference of the results at trachea and right main stem bronchus was statistically significant (P <0.05),the over-all results was not significant difference between CT and bronchoscopy examination (P =0.340).Associated findings included em-physema in 74 cases,pneumonia in 48 cases,atelectasis in 22 cases,mediastinal displacement in 57 cases,lung interstitial emphyse-ma in 4 cases,pneumomediastinum and pneumoderma in 4 cases,bronchiectasis in 2 cases,and pleural effusion in 4 cases.Conclu-sion MSCT and its postprocessing techniques can accurately and intuitively display the tracheobronchial foreign body and complica-tions,which has important value for clinical application.
