With high prevalence and high burden, the condition we call 'chronic obstructive pulmonary
disease'(COPD) is not so much a respiratory concern as a public-health epidemic (1). This is …

Abstract Background and Objective Mucus plugs and underlying airway tree structure can
affect airflow limitation and prognosis in patients with chronic obstructive pulmonary disease …

Background Lung hyperinflation in chronic obstructive pulmonary disease (COPD) is closely
associated with emphysema and non-emphysematous gas trapping, termed functional small …

Purpose To develop a novel method for calculating small airway resistance using
computational fluid dynamics (CFD) based on CT data and evaluate its value to identify …

Objectives Micro–computed tomography (micro-CT) is a novel, nondestructive, slide-free
digital imaging modality that enables the acquisition of high-resolution, volumetric images of …

Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease characteristic of
