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

Quantitative computed tomography is being increasingly used to quantify the features of
chronic obstructive pulmonary disease, specifically emphysema, air trapping, and airway …

The purpose of this statement is to describe and define the phenotypic abnormalities that
can be identified on visual and quantitative evaluation of computed tomographic (CT) …

Lung densitometry assesses with computed tomography (CT) the X-ray attenuation of the
pulmonary tissue which reflects both the degree of inflation and the structural lung …

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 …

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

RATIONALE AND OBJECTIVES: Computed tomography (CT) section thickness and
reconstruction kernel each influence CT measurements of emphysema. This study was …

Background: Chronic obstructive pulmonary disease (COPD) is characterised by the
presence of airflow limitation caused by loss of lung elasticity and/or airway narrowing. The …

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

Rationale: Computed tomography (CT)-based lung density is used to quantitate the
percentage of emphysema-like lung (hereafter referred to as percent emphysema), but …
