支气管扩张(支扩)是支气管局部或全部呈不可逆性的扩张。支扩分三种形态:柱状、扭曲状和囊状。本文就各支气管肺段进行 CT 与支气管造影的对照检查,以评价作为非侵袭性技术的 CT 在支扩诊断上的作用。疑有支扩的14例病人作胸部平片、CT 和支气管造影检查。女9人,男5人,年龄28～70岁(平均49岁)。其中3例另加作 CT 薄层(1.5mm)扫描。支扩的 CT 诊断按1982年 Naidich 提出的诊断标准。12例患 Bronchiectasis (branch expansion) is the bronchial expansion of some or all of the irreversible. Branch expansion in three forms: columnar, twisted and cystic. This article examines the bronchial segment of bronchial CT and bronchial contrast examination to evaluate the non-invasive CT in the expansion of the role in the diagnosis. 14 cases of suspected expansion with chest radiographs, CT and bronchography. 9 females, 5 males, aged 28 to 70 years (mean 49 years). Three of them were additionally made of CT thin-layer (1.5mm) scans. CT diagnosis of branch expansion by the 1982 diagnosis proposed by Naidich. 12 patients
