Chronic Pulmonary Obstructive Disease (COPD) On High Resolution Computed Tomography

Abstract

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.
