Computed tomography (CT) scanning allows precise assessment of both the extent and
distribution of emphysema. There has been little work on the relationship between the …

Emphysema distribution is associated with chronic obstructive pulmonary disease. It is,
however, unknown whether computed tomography (CT)-quantified emphysema distribution …

OBJECTIVE. The purpose of this study was to compare quantitative and visual assessments
of regional heterogeneity of emphysema and to investigate the influence of regional …

Rationale: Emphysema occurs in distinct pathologic patterns, but little is known about the
epidemiologic associations of these patterns. Standard quantitative measures of …

Purpose To provide quantitative information on emphysema in asymptomatic smokers in
correlation with pulmonary function tests (PFT). Patients and methods The study population …

Volumetric computed-tomography scans allow diagnosis and quantification of the individual
small airway and emphysema phenotypes present in people with chronic obstructive …

Background Pulmonary emphysema is divided into 3 major subtypes at autopsy:
centrilobular, paraseptal, and panlobular emphysema. These subtypes can be defined by …

Purpose: To prospectively compare pulmonary function tests and helical computed
tomographic (CT) indexes for quantifying pulmonary emphysema with macroscopic and …

Purpose To determine whether visually assessed patterns of emphysema at CT might
provide a simple assessment of mortality risk among cigarette smokers. Materials and …

OBJECTIVE. The aim of this study was to identify ancillary morphologic features on high-
resolution CT that modify airflow obstruction and gas transfer levels in individuals with …
