单排螺旋CT对小儿气管支气管异物的诊断应用价值

Diagnosis of tracheobronchial foreign body in children with single-slice helical CT and coronal position scanning

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 explore the diagnostic value of the single-slice helical CT in pediatric tracheobronchial foreign body wlih coronal position plain-scanning.Methods Retrospective analysis 70 children were treated of tracheobronchial foreign body in our hospital,everyone was by single-slice helical CT examined with coronal scanning.70 routine rigid bronchoscopy results in line with the CT examination.Results 70 cases of childen,According to CT diagnosis：tracheal foreign body in 5 cases,the right bronchus in 37 cases,the left bronchus in 27 cases,double bronchus in 1 cases.70 routine rigid bronchoscopy results in line with the CT examination,68 cases are in line,2 cases are not,diagnosis in line with the rate of 97.1%.Conclusion Single-slice helical CT with coronal scanning is a sure clinical value method of examination in pediatric trachobronchial foreign body in diagnosis,it can show tracheobronchial foreign body for children directly.
