摘要
目的探讨支气管扩张症的DR表现,旨在提高DR对支气管扩张疑似病例的诊出水平。方法对比分析46例支气管扩张症患者每一个病灶(以肺段为单位)的DR及CT资料。结果经CT确诊支气管扩张的46例患者共有187个病灶;DR诊断疑似支气管扩张患者42例(91.3%)共有病灶137个(73.2%),其中DR检出柱状型88个(66.7%);囊状型病灶14个(100%),曲张型7个(87.5%);混合型28个(80%)。结论不同类型及不同肺段支气管扩张有不同的DR特征。抓住特征影像拟诊出支气管扩张疑似病例进行CT检查,是减少本病漏诊的关键。
Objective To evaluate the efficacy of digital radiography （DR） for detecting bronchiectasis. Methods The DR and CT features of 46 patients with bronchiectasis were correlated. Results Of 187 bronchiectatic lesions in 46 patients demonstrated on CT, 137 （73.2%） lesions in 42 patients （91.3%） were detected on DR. The bronchiectasis identified on DR was cylindrical （88 lesions, 66.7% ）, cystic （14, 100% ）, varicose （7, 87.5% ）, and mixed （28, 80%）. Conclusions DR features are variable according to the type of bronchiectasis and the segmental location in the lungs. These features help to identify the patients who require CT for further evaluation.
