【摘要】 目的 评价螺旋CT诊断支气管扩张症的价值。方法 对经胸科手术或呼吸科随访观察确诊支气管扩张症的33例患者的8mm层厚的螺旋CT扫描及2mm层厚的螺旋CT薄层扫描图像进行对比分析。结果 33例患者中螺旋CT常规扫描(8mm层厚)诊断支气管扩张症16例37个肺段，其中柱状型4例，静脉曲张型2例，囊状型3例和混合型7例。2mm层厚薄层扫描诊断支气管扩张症33例136个肺段，其中柱状型14例，静脉曲张型5例，囊状型3例和混合型11例。结论 螺旋CT薄层扫描对支气管扩张的检测具有更高的敏感性、特异性及准确性，可作为诊断支气管扩张症的首选检查方法。

    【Abstract】 Objective To evaluate the value of Spiral Computed Tomography(SCT)in diagnosing bronchiecˉtasis.Methods Thirty-three patients with bronchiectasis confirmed by surgical intervention in department of thoracic surgery or following up patients’condition in department of respiratory medicine were selected as the object of this study.The initial radiologic examination was performed by a SCT scan with8mm and1.5-2.0mm thick section.All images were analysed retrospectively.The diagnostic results of the SCT scan with8mm thick section were comˉpared to those of the SCT scan with2.0mm hick section.Results The SCT images with8mm thick section showed16cases bronchiectasis with37lung segments in33patients ......
