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

Background In the 2014 Global initiative for chronic Obstructive Lung Disease guidelines,
bronchiectasis was for the first time defined as a comorbidity of chronic obstructive …

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) …

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

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

Computed tomography (CT) is the modality of choice for imaging the lungs in vivo. Sub-
millimeter isotropic images of the lungs can be obtained within seconds, allowing the …

Purpose To develop a deep learning–based algorithm to stage the severity of chronic
obstructive pulmonary disease (COPD) through quantification of emphysema and air …

Background Imaging variables, including airway diameter, wall thickness, and air trapping,
have been found to be important metrics when differentiating patients with severe asthma …

Objectives: Automated computational segmentation of the lung and its lobes and findings in
X-Ray based computed tomography (CT) images is a challenging problem with important …

Background The aim of the study was to assess the relationship between computed
tomography (CT) densitometry and routine clinical markers in patients with chronic …
