摘要

慢性阻塞性肺疾病(COPD)是一种流行的、可预防和可治疗的慢性肺部疾病,可以在HRCT上准确检测到,它影响着全世界的男性和女性。目的:探讨高分辨率计算机断层扫描对慢性肺阻塞性疾病(COPD)的诊断特点。方法:本研究纳入120例COPD患者,至少有全面的临床记录为6MWT,经支气管扩张剂后FEV1/FVC 70%定义为COPD,持续呼气流量受限。采用方便入路计算120例患者的样本量,并使用64张载片从肺尖到横膈膜进行非对比HRCT扫描。肺气肿评分和-950 HU标准用于自动划分肺,不包括中央气道。数据在SPSS version 22上输入和分析。结果:HRCT扫描示支气管实质带征9例(7.5%)伴支气管壁增厚,结节24例(20%),支气管扩张23例(19%),根尖纤维化19例(15%),树芽型12例(10%)。结论:慢性阻塞性肺疾病常见于男性,吸烟或吸烟者病情加重,主要表现为实质带、支气管壁增厚、结节、支气管扩张、根尖纤维化和芽上树型。

Chronic Pulmonary Obstructive Disease (COPD) On High Resolution Computed Tomography
The prevalent, preventable, and treatable chronic lung illness known as chronic obstructive pulmonary disease (COPD), which may be accurately detected on HRCT, affects both men and women worldwide. Objective: To evaluate the diagnostic features of chronic pulmonary obstructive disease (COPD) using high resolution computed tomography. Methods: This study included 120 patients with COPD at least having a comprehensive clinical record of 6MWT defined as COPD by a post-bronchodilator FEV1/FVC 70% with sustained expiratory flow limitation. The sample size was computed at 120 patients using convenient approach and non-contrast HRCT was performed using 64 slides scanning from the apex of the lung to the diaphragm. Emphysema scoring and -950 HU criteria were used to automatically partition the lungs without including the central airways. The data were entered and analyzed on SPSS version 22. Results: HRCT scan findings show that patients with parenchymal bands were 9(7.5%) with bronchial wall thickening, nodules were (24)20%, bronchiectasis were (23)19%, apical fibrosis were (19)15%, and tree on bud pattern were (12)10%. Conclusions: It is concluded that COPD is common in males and worsens in cigarette or tobacco smokers, with a prevalence of parenchymal bands, bronchial wall thickening, nodules, bronchiectasis, apical fibrosis, and tree-on-bud patterns.
