Longitudinal changes in structural abnormalities using MDCT in chronic obstructive pulmonary disease

Backgroud: Multi-detector computed tomography (MDCT) can detect the loss of lung tissue associated with emphysema as a low-attenuation area (LAA) and the thickness of airways as the wall area percentage (WA%). The percentage of small pulmonary vessels less than 5 mm2 (%CSA<5) has been recently recognized as a parameter for expressing pulmonary perfusion. Objective: We aimed to analyze the longitudinal changes in structural...
