Purpose To provide a new detailed visual assessment scheme of computed tomography
(CT) for chronic obstructive pulmonary disease (COPD) by using standard reference images …

The Genetic Epidemiology of Chronic Obstructive Pulmonary Disease (COPDGene) study,
which began in 2007, is an ongoing multicenter observational cohort study of more than …

Purpose To test the hypothesis—given the increasing emphasis on quantitative computed
tomographic (CT) phenotypes of chronic obstructive pulmonary disease (COPD)—that a …

Background COPD is a heterogeneous disease characterized by airflow obstruction and
diagnosed by lung function. CT imaging is emerging as an important, noninvasive tool in …

Background The value of quantitative CT (QCT) to identify chronic obstructive pulmonary
disease (COPD) phenotypes is increasingly appreciated. The authors hypothesised that …

We investigated how quantitative high-resolution computed tomography (HRCT) measures
of emphysema and airway wall thickness (AWT) vary with sex, age and smoking history. We …

Background The clinical characteristics of patients with emphysema but without airway
limitations remain unknown. The goal of this study was to compare the clinical features of …

Rationale Predicting increased risk of future healthcare utilization in chronic obstructive
pulmonary disease (COPD) patients is an important goal for improving patient management …

Chronic obstructive pulmonary disease (COPD) is characterized by the presence of airflow
limitation that is caused by a combination of small airway remodeling and emphysema …

The objectives of the present study were to reappraise chest radiography for the diagnosis of
emphysema, using computed tomography (CT) as the reference standard, and to establish …
