中国卫生产业US T R Y多层螺旋CT 三维重建对不同部位儿童气管支气管异物的诊断价值段效军陈艳萍仇君湖南省儿童医院,湖南长沙410007[摘要]目的探讨多层螺旋CT 三维重建对不同部位儿童气管支气管异物的诊断价值。
方法回顾性分析湖南省儿童医院2011年9月至2013年2月经纤维支气管镜检查并确诊为儿童气管支气管异物的患儿114例,所有患儿检查前均行胸部多层螺旋CT 三维重建。
结果气管异物病例的CT 阳性率最低(7.70%),其次为叶及叶以下支气管异物病例,CT 阳性率为58.33%,右主支气管异物、左主支气管异物病例的CT 阳性率相对较高,分别为81.82%、74.19%,差异有统计学意义(χ2=34.82,P <0.0001)。
结论多层螺旋CT 三维重建对不同部位儿童气管、支气管异物的诊断价值存在差异,气管异物CT 阳性率低,易漏诊、误诊,需尽早行支气管镜检查确诊。
