The present study aimed to propose a method to quantify the loss of lung tissue mass (LTM) in regions of low X-ray attenuation and to evaluate the increase of LTM in regions of high attenuation using the quantitative analysis of computed tomography (CT) images of patients with emphysema from different etiologies. Thus, 16 subjects with alpha-1 antitrypsin deficiency emphysema (A1ATD), 21 with emphysema due to smoking (Non-A1ATD) and 27 healthy individuals with no smoking history (Control) were studied. The volunteers underwent pulmonary function tests (PFT) and underwent CT imaging during inspiration and expiration. The LTM content associated with 3, 15 and 50% (M3, M15 and M50) fractions of total lung capacity (TLC) and the complement of t...
