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.
