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

Objective To determine the incidence of subtypes of pulmonary emphysema (PE) identified
by CT imaging in male patients who have a significant smoking history. Patients and setting …

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

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 …

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

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 …

Background The clinical significance of visually evident emphysema on CT images in
individuals without spirometric evidence of chronic obstructive pulmonary disease (COPD) …

Rationale: Chronic obstructive pulmonary disease (COPD) is characterized by airflow
limitation, caused by emphysema and small airways disease (SAD). Computed tomography …
