对53例慢性阻塞性气道疾病患者和19例年龄匹配的对照组进行了计算机断层扫描（CT）研究。CT可以发现肺气肿的存在和分布。胸片上可检测到的肺血管改变与CT测量的肺密度有很好的相关性。肺气肿CT变化明显的患者弥散能力和FEV1.0/VC [1-s用力呼气量/肺活量]的损害明显大于变化不严重的患者。
Patients (53) with chronic obstructive airways disease and 19 age-matched controls were studied with computed tomography (CT). CT can detect the presence and distribution of pulmonary emphysema. Pulmonary vascular changes detectable on chest radiography correlate well with lung density as measured by CT. Patients with marked CT changes of emphysema had significantly greater impairment of diffusion capacity and FEV1.0/VC [1-s forced expiratory volume/vital capacity] than did the patients with less severe changes.
