摘要 目的探讨应用低剂量128层CT诊断小儿气道非金属异物的应用价值。方法回顾性分析经支气管内镜检取异物的40例小儿气管支气管非金属异物患者的128层螺旋CT影像学资料。128层CT低剂量扫描选用个体化方案,记录每位患儿的平均有效剂量(mGy),将容积数据进行多平面重组(MPR)、曲面重组(CPR)、最小密度投影(Min-IP),并将CT与内镜结果对比分析。结果 128层CT发现异物26例位于隆突上方;位于右侧主支气管及远端8例;左侧主支气管及远端4例;2例患儿左右支气管均发现异物,诊断中的敏感度、准确度分别为100%、90%。结论小儿气管支气管非金属异物128层CT低剂量扫描能满足诊断,准确评估异物大小、位置、形态及肺部并发症,能减少不必要的支气管镜检及弥补X线平片的不足,具有重要的临床应用价值。
