摘　　要：目的探讨高分辨率CT在儿童闭塞性毛细支气管炎(BO)中的应用价值。方法回顾性分析经临床证实的38例BO患儿的影像资料,所有患儿均行肺部高分辨率CT扫描。结果 38例患儿,均不同程度具备"马赛克"灌注征像,呈弥漫性多发片状分布,部分边界清晰,部分模糊,少部分清晰与模糊并存。血流灌注减少35例;肺内气体潴留37例;支气管壁增厚21例、支气管扩张23例,二者均以下叶发病最高;单侧或局限性透明肺7例;肺实质病变25例,其中肺不张11例、肺炎13例、肺实变11例;肺内结节16例、胸膜下结节7例;支气管粘液栓3例。结论高分辨率CT能够对儿童BO各种征象进行直观显示,其中以"马赛克"灌注最为典型,为本病的首要影像学表现,从而能够更早的为临床治疗提供依据。高分辨率CT是儿童BO不可缺少的一种影像学检查手段。Objective To explore the applicative value of high resolution CT（HRCT） in the treatment of bronchiolitis obliterans（BO） in children.Methods The pulmonary HRCT findings of 38 cases with clinically confirmed BO were retrospectively analyzed. Results All the 38 cases had ＂mosaic＂ perfusion signs to different degrees, which displayed a diffuse and patchy distribution, and some cases showed clear boundary, some fuzzy, while in other cases both conditions exist. Blood perfusion in35 cases decreased, and pulmonary air trapping, bronchial wall thickening, and bronchial dilatation were found in 35, 21 and23 cases respectively, the latter two of which have a higher incidence in the lower lobe. 7 cases had unilateral hyperlucent lung,and 25 cases had pulmonary parenchyma, including 11 cases of atelectasis, 13 cases of pneumonia, and 11 cases of pulmonary consolidation. Lung nodules were found in 16 cases, subpleural nodules in 7 cases, and bronchial mucus plugs 3 cases.Conclusion HRCT could directly display all sorts of signs of BO in children, wherein the most typical symptom and the primary imaging feature of these diseases is the ＂mosaic＂ perfusion pattern. Therefore, HRCT can provide the basis for earlier clinical treatment, and it is an indispensable imaging examination method in children BO treatment.
