Dynamic computed tomography (CT) was performed in nine patients with enlarged bronchial arteries documented by arteriography. Plain and contrast-material-enhanced CT scans of two more patients with prominent bronchial arteries were retrospectively reviewed. The study was conducted to determine visibility of the bronchial artery with CT and to depict the anatomic relationship of its mediastinal portion to surrounding structures. The mediastinal portion of the bronchial artery was successfully outlined as nodular or linear densities on all dynamic CT scans. The right bronchial artery was confirmed to arise from the medial wall of the thoracic aorta, whereas the left arises from the anterior wall. Because of its retroesophageal location, the enlarged right bronchial artery can compress the posterior wall of the esophagus. It is postulated that the left bronchial artery occasionally traverses the aorticopulmonary window, recognized as nodular or linear densities below the aortic arch on CT scans.
对9例经动脉造影证实支气管动脉增粗的患者进行了动态计算机断层扫描（CT）。对另外2例支气管动脉突出的患者的平扫和对比剂增强CT扫描进行了回顾性分析。本研究旨在确定CT对支气管动脉的显示情况，并描绘其纵隔部分与周围结构的解剖关系。在所有动态CT扫描中，支气管动脉的纵隔部分均成功显示为结节状或线状密度影。右支气管动脉被证实起自胸主动脉内侧壁，而左支气管动脉起自前壁。由于其位于食管后方，增粗的右支气管动脉可压迫食管后壁。据推测，左支气管动脉偶尔会穿过主动脉肺动脉窗，在CT扫描上表现为主动脉弓下方的结节状或线状密度影。
