目的利用单排螺旋CT,采用冠状位平扫,探讨其对小儿气管支气管异物的诊断应用价值。方法分析我院70例小儿气管支气管异物单排螺旋CT冠状位扫描的影像表现,并与支气管镜检查所见结果进行对照。结果 70例患儿中,CT诊断气管内异物5例,右侧支气管内异物37例,左侧支气管内异物27例,1例双侧支气管内异物。经支气管镜检查,68例符合,2例未取出异物。CT诊断符合率97.1%。结论用单排螺旋CT,采用冠状位扫描,对直接显示小儿气管支气管异物,具有确定的临床诊断价值。
Objective To evaluate the value of coronary angiography in the diagnosis of tracheobronchial foreign bodies in children by single-slice spiral CT. Methods Analysis of 70 cases of pediatric tracheobronchial foreign bodies single-slice spiral CT coronal scan imaging performance and bronchoscopy findings were compared. Results Among the 70 children, CT was diagnosed as 5 cases of endotracheal foreign body, 37 cases of right bronchial foreign body, 27 cases of left bronchial foreign body and 1 case of bilateral endobronchial foreign body. Bronchoscopy, 68 cases of compliance, 2 patients did not remove foreign body. The coincidence rate of CT diagnosis was 97.1%. Conclusion Single-slice spiral CT, using coronal scan, the direct display of children with tracheal bronchial foreign body, with a definite clinical diagnostic value.
