OBJECTIVE. The purpose of our study was to determine the attenuation threshold value for
the detection and quantification of air trapping using paired inspiratory and expiratory …

OBJECTIVE. The purpose of this study was to determine whether measurements of lung
attenuation at inspiration and expiration obtained from 3D lung reconstructions reflect the …

Objectives To determine the relationship between lung function impairment and quantitative
computed tomography (CT) measurements of air trapping and emphysema in a population …

Quantitative computed tomography is being increasingly used to quantify the features of
chronic obstructive pulmonary disease, specifically emphysema, air trapping, and airway …

The authors assess the utility of postexpiratory high-resolution computed tomography
(HRCT) scans in the evaluation of air trapping in patients with obstructive lung disease …

We studied 80 subjects (63 M, 17 F; 23-82 yrs) and related lung computerized tomography
(CT) density with age, height, spirometry, lung volumes, diffusing capacity and arterial blood …

OBJECTIVE. This study evaluates the relationships between quantitative CT (QCT) and
spirometric measurements of disease severity in cigarette smokers with and without chronic …

Objectives: We examined the hypothesis that paired inspiratory/expiratory computed
tomography (CT) scans in a limited-lung area that excludes emphysema may provide a …

Purpose To correlate currently available quantitative CT measurements for airway disease
with physiological indices and the body-mass index, airflow obstruction, dyspnea, and …

Objectives One objective was to evaluate the air trapping index (ATI), measured by
inspiration/expiration CT, in COPD patients and nonsmokers. Another objective was to …
