Longitudinal changes in structural lung abnormalities using MDCT in COPD with asthma-like features

Background: Some patients with COPD have asthma-like features. However, few reports have shown the structural lung abnormalities found in this population. Multi-detector computed tomography (MDCT) can detect emphysematous low-attenuation areas (LAA), airway thickness (wall area percentage, WA%), and the loss of pulmonary vasculature as the percentage of small pulmonary vessels less than 5 mm² (%CSA<5). Aims: We aimed...
