Abstract:
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.
