摘　　要：目的：探讨肺部高分辨力CT（HRCT）在儿童支气管哮喘诊断中的应用价值。方法：回顾性分析19例支气管哮喘患儿的 HRCT资料，年龄3～10岁，男12例，女7例。结果：19例支气管哮喘患儿中，HRCT 显示空气潴留15例（79％），支气管壁增厚12例（63％），支气管扩张6例（31％），局限性肺不张3例（16％），粘液嵌塞2例（11％），纵隔旁肺气肿1例（5％），完全未见异常征象3例（16％），肺部总阳性率84％（16／19）。结论：儿童支气管哮喘的肺部 HRCT 有较多特征性改变，对诊断儿童支气管哮喘具有较大应用价值。Objective：To investigate the application of high resolution CT （HRCT）of the lungs in the diagnosis of bronchial asthma in children.Methods：HRCT images of 19 children with bronchial asthma aged 3 to 10 years,including 12 males and 7 females were analyzed retrospectively.Results：Of the 1 9 children with bronchial asthma,HRCT showed air re-tention in 15 cases （79%）,bronchial wall thickening in 12 cases （63%）,bronchiectasis in 6 cases （31%）,focal atelectasis in 3 cases （1 6%）,mucous impaction in 2 cases （1 1%）,paramediastinal emphysema in one case （5%）.No abnormal changes were seen in 3 cases （16%）.Positive rate of the lungs in 19 children was 84% （16/19）.Conclusion：HRCT of the lungs in children with bronchial asthma can rveal many characteristic changes,which was useful for the diagnosis of bronchial asth-ma in children.
