摘要
目的 探讨多排螺旋CT（multi—slice spiral CT，MSCT）及多平面重建（multiplanar reformation，MPR）技术、曲面重建（curve multiplanar reformation，CPR）技术在小儿支气管异物影像诊断中的价值。方法 确诊支气管异物患儿10例，男孩9例，女孩1例，年龄为（1．2～10．0）岁；在常规螺旋CT检查的基础上，再结合MPR，CPR显示支气管狭窄、异物及其所在的位置，以及异物阻塞所致的间接征象。结果 螺旋CT检查结果提示，支气管异物并经支气管镜检确诊，位于右侧主支气管者8例，位于左侧主支气管者2例；低密度异物8例，包括花生米3例、开心果皮、玉米粒、瓜子仁、蚕豆和肉丝各1例，高密度异物，如牙齿和鱼刺残留各1例；螺旋CT检查结果显示，肺炎7例，肺不张4例，肺气肿3例，纵隔气肿4例，皮下气肿4例，气胸2例。结论 螺旋CT加MPR／CPR技术对小儿支气管异物的显示率高，定位准确，并可显示各种合并症，对气道异物的诊断和鉴别诊断有极重要的价值。
Objective To discuss the value of MSCT and MPR,CPR in dignosis of bronchial foreign body of children. Methods 10 cases of bronchus foreign body,including 9 boys and 1 girl aged 1.2-10.0 years old, were given axial CT scan, MPR and CPR, which shew bronchial stenosis, foreignbody and their locations,indirect sign of blockage. All patients were examed with bronchoscopy after CT scan. Results There were 8 cases located right primary bronchus and 2 cases left primary bronchus;8 cases of foreign bodies with low density,including peanut kernel 3 cases, pistachios clothes 1 case, corn 1 case, melon seeds 1 case,bean 1 case and shredded meat 1 case ,as 2 cases with high density which were tooth 1 case and fish thron 1 case. CT shew pneumonia 7 cases, pulmonary closure 4 cases, pneumonectasia 3 cases,mediastinal emphysema 4 cases,cutaneous emphysema 4 cases and aeropleura 2 cases. Conclusion Bronchus foreignbody in children can be shew clearly and located accurately by using MSCT, MPR and CPR, as various kinds of complication, which have great value in dignosis and differential diagnosis of bronchus foreign body.
