作者以HRCT作对照组比较螺旋CT诊断支扩的敏感性。本组病例包括31例门诊病人,男17例,女14例,平均年龄53.4岁。所有病例均反复下呼吸道感染,间断咯血或慢性咳嗽,临床怀疑支扩。作者分析支扩的影像表现有以下三种:柱状扩张,指层面内支气管呈“轨道”或“印戒”样;静脉曲张样支气管扩张,表现为支气管内径扩大稍明显且壁不规则呈“串珠”样;囊状扩张,可见气液平面及成串或成簇的多个囊腔。
The authors compared HRCT as a control group to compare the sensitivity of spiral CT in detecting dilatation. The patients included 31 outpatients, 17 males and 14 females, with an average age of 53.4 years. All cases were repeated lower respiratory tract infection, intermittent hemoptysis or chronic cough, clinical suspicion of expansion. The authors analyze the following three manifestations of branch expansion: columnar expansion, refers to the level of the bronchus was “track” or “signet ring” like; varicose-bronchiectasis, manifested as slightly enlarged bronchial diameter and irregular wall was “beaded ”Like; cystic dilatation, visible gas-liquid level and a plurality of clusters or clusters of cysts.
