    [摘要]慢性阻塞性肺疾病是一种临床常见病，肺功能检查作为诊断慢性阻塞性肺疾病(COPD)的金标准，存在重症患者配合欠佳难以完成检查等问题。CT检查具有较高分辨率，能较好显示COPD患者肺部的主要病变及其继发征象，然而，常规CT检查主要依靠放射科医生主观评估，受个人经验等影响较大，且无法对COPD患者肺气肿等病变进行具体量化，随着影像学检查技术及计算机后处理技术的不断发展，越来越多学者对CT定量测量展开了研究，CT定量测量在显示肺气肿病变及小气道方面具有独特优势，并能对患者的并发症进行详细评估，实现了从肉眼观察到定量评估的转换，本文将从CT定量测量在COPD中的应用展开综述，探讨其诊断及临床应用价值。

    [Abstract] Chronic obstructive pulmonary disease (COPD)is a common clinical disease. As a gold standard for diagnosing COPD，pulmonary function examination has some problems，such as poor cooperation of severe patients and difficulty in completing the examination. CT examination has high resolution ......
