Computed tomography (CT) was performed on six patients with bronchiectasis. In two cases of advanced cystic bronchiectasis, the diagnosis was apparent on plain chest roentgenograms. In four cases, bronciectasis was initially diagnosed by CT and later confirmed by bronchography. The CT signs of bronchiectasis include air--fluid levels in distended bronchi, a linear array or cluster of cysts, dilated bronchi in the periphery of the lung, and bronchial wall thickening due to peribronchial fibrosis. Distended bronchi must be distinguished from emphysematous blebs, which generally have no definable wall thickness and no accompanying vessels. It is concluded that CT should have a role in establishing the presence and anatomic extent of bronchiectasis.
对6例支气管扩张患者进行了计算机断层扫描（CT）检查。在2例晚期囊状支气管扩张病例中，胸部X线平片上诊断明确。在4例病例中，支气管扩张最初由CT诊断，随后经支气管造影证实。支气管扩张的CT表现包括扩张支气管内的气液平面、线性排列或成簇的囊肿、肺周边的扩张支气管以及支气管周围纤维化导致的支气管壁增厚。扩张的支气管必须与肺大疱相鉴别，肺大疱通常没有可明确界定的壁厚且无伴随血管。结论是CT在确定支气管扩张的存在及解剖范围方面应发挥作用。
