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

The purposes of this study were: to describe chest CT findings in normal non-smoking
controls and cigarette smokers with and without COPD; to compare the prevalence of CT …

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

OBJECTIVE: To assess whether high-resolution computed tomography (HRCT) variables
are as good as other known clinical variables in grading emphysema patients. METHODS: A …

Background CT scan measures of emphysema and airway disease have been correlated
with lung function in cohorts of subjects with a range of COPD severity. The contribution of …

To investigate whether lung function in patients with chronic obstructive pulmonary disease
(COPD) can be directly predicted using CT densitometric measures and assess the …

Chronic obstructive pulmonary disease (COPD) is described as airflow limitation that is not
fully reversible. Quantitative assessment of structural changes within the lung that are …

CT scans of 474 patients with suspected chronic obstructive pulmonary disease (COPD)
were retrospectively evaluated by automated software. There was a correlation between the …

Rationale: Quantitative computed tomography (CT) has been used to phenotype patients
with chronic obstructive pulmonary disease (COPD). A mixed phenotype is defined as the …

Background Emphysematous change as assessed by CT imaging has been reported to
correlate with COPD prognostic factors such as FEV 1 and diffusing capacity of the lung for …
