Lung air trapping is estimated via quantitative computed tomography (CT) using density
threshold-based measures on an expiration scan. However, the effects of scanner …

Background Pulmonary endothelial damage has been shown to precede the development
of emphysema in animals, and vascular changes in humans have been observed in COPD …

BACKGROUND COPD includes the chronic bronchitis (CB) and emphysema phenotypes.
Although it is generally assumed that emphysema or chronic airflow obstruction (CAO) is …

Among the various imaging modalities available, CT has remained over time the core
imaging technique for the evaluation of respiratory disorders. The recent advent of dual …

Purpose: The purpose of this study was to detect and analyze anomalies between a large
number of computed tomography (CT) scanners, tracked over time, utilized to collect human …

Since the lung receives the entire cardiac output, sophisticated imaging techniques are not
required in order to measure total organ perfusion. However, for many years studying lung …

Increasingly, quantitative lung computed tomography (qCT)-derived metrics are providing
novel insights into chronic inflammatory lung diseases, including chronic obstructive …

The ability to measure airway dimensions is important for clinicians, interventional
bronchoscopists and researchers in order to accurately quantify structural abnormalities and …

Background Air pollution alters small pulmonary vessels in animal models. We hypothesised
that long-term ambient air pollution exposure would be associated with differences in …

Global measurements of the lung provided by standard pulmonary function tests do not give
insight into the regional basis of lung function and lung disease. Advances in imaging …
