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

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

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

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

Background Emphysema and small airway disease both contribute to chronic obstructive
pulmonary disease (COPD), a disease characterised by accelerated decline in lung …

Background Cigarette smoking is associated with emphysema and radiographic interstitial
lung abnormalities. The degree to which interstitial lung abnormalities are associated with …

Background The relationship between emphysema progression and long-term outcomes is
unclear. Purpose To determine the relationship between emphysema progression at CT and …

We assessed with computed tomography (CT) densitometry the prevalence of emphysema
in 266 (175 men and 91 women; mean age 64±4 years) smokers and former smokers …

Background The correlation between visual emphysema patterns and subsequent
progression of disease may provide a way to enrich a study population for treatment trials of …

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