摘要
目的探讨低剂量螺旋CT在小儿麻疹肺炎中的应用并分析其影像特点。方法回顾性分析经临床确诊为麻疹肺炎的患儿47例,所有患儿均行低剂量螺旋CT扫描,分析其CT图像特点。结果CT表现为肺过度充气19例,支气管血管束增粗47例,并间质网织结节影31例,结节影大小、密度及分布不甚均匀,以中内带肺野明显,并气胸3例,皮下、纵膈气肿1例。结论低剂量螺旋CT可应用于小儿麻疹肺炎的诊断,以肺过度充气和间质纹理增多、小结节影为主要表现。
Objective To discuss the application of low-dose spiral CT in children with measles pneumonia and summarize the imaging feastures.Methods Retrospectively analyzed the clinical diagnosis of measles pneumonia in 47 cases, all of which underwent low dose spiral CT scanning. The CT image characteristics were analyzed.Results CT manifestations of pulmonary hyperinflation in 19 cases, bronchovascular bundle thickening in 47 cases, and interstitial reticulum nodules in 31 cases. The size, density and distribution of nodules are not uniform, obviously in lungs. There were 3 cases of pneumothorax, 1 case of subcutaneous and mediastinal emphysema.Conclusion Low dose spiral CT can be used in diagnosing children with measles pneumonia. Pulmonary hyperinlfation and interstitial markings, small nodules were the most common imaging features of children with measles pneumonia.
