摘　　要：目的探讨螺旋CT三维重建技术在儿童呼吸道异物诊断中的应用价值。方法对可疑儿童呼吸道异物进行螺旋CT扫描及三维重建,结果作为研究组;以气管镜检查结果作为金标准,X线胸片或胸透检查结果作为对照组,通过χ2检验比较两组与金标准符合情况。结果螺旋CT三维重建可清楚显示病变部位、范围、有无继发感染,其阳性率高于对照组,差异具有统计学意义(P<0.05)。结论螺旋CT三维成像技术是诊断儿童呼吸道异物的重要依据。Objective To evaluate the value of spiral CT three dimensional （3D） reconstructions in the diagnosis of tracheo - bron- chial foreign bodies in children. Methods The spiral CT scan and 3D reconstruction images were regarded as the study group,and chest X - ray and fluoroscopy examinations as the control group. The results were compared with the gold standard of tracheoscope examination using the Chi - square test. Results 3D reconstructions of spiral CT could well display the location, range and secondary infection of tra- cheo - bronchial foreign bodies, which had a high positive proportion and stastistical significance （P 〈 0.05 ）. Conclusion 3D recon- struction technique of spiral CT is valuable in the diagnosis of tracheobronchial foreign bodies in children.
