Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease that is
characterized by chronic airflow limitation. Unraveling of this heterogeneity is challenging …

Purpose To correlate currently available quantitative CT measurements for airway disease
with physiological indices and the body-mass index, airflow obstruction, dyspnea, and …

Background and objective The prevalence of lung cancer has been increasing in healthy
elderly patients with preserved pulmonary function and without underlying lung diseases …

Objectives To determine the optimal threshold by quantitatively assessing the extent of
emphysema at the level of the entire lung and at the level of individual lobes using a large …

We evaluated pulmonary sequelae in COVID-19 survivors by quantitative inspiratory–
expiratory chest CT (QCT) and explored abnormal pulmonary diffusion risk factors at the 6 …

Background Gas trapping quantified on chest CT scans has been proposed as a surrogate
for small airway disease in COPD. We sought to determine if measurements using paired …

Computed tomography (CT) is the modality of choice for imaging the thorax and lung
structure. In chronic obstructive pulmonary disease (COPD), it used to recognise the key …

Background Beyond lung cancer, screening CT contains additional information on other
smoking related diseases (eg chronic obstructive pulmonary disease, COPD). Since …

Background COPD is a complex, heterogeneous disease characterised by progressive
development of airflow limitation. Spirometry provides little information about key aspects of …

BACKGROUND COPD has traditionally been defined by the presence of irreversible airflow
limitation on spirometry using either the GOLD (Global Initiative for Chronic Obstructive Lung …
