The purposes of this study were: to describe chest CT findings in normal non-smoking
controls and cigarette smokers with and without COPD; to compare the prevalence of CT …

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 …

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

Computed tomography (CT) has contributed substantially to our understanding of COPD
over the past decade. Visual and quantitative assessments of CT in COPD are …

BACKGROUND: COPD patients have varying degrees of airways disease and emphysema.
CT scanning can differentiate these pathological subtypes. We evaluated airway dimensions …

differences in disease pathogenesis and further enable the classification of subjects with …

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) …

Background The contribution and role of emphysema and small airways disease in causing
expiratory airflow limitation in COPD is controversial. Methods We obtained high-resolution …

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 …
