Apparently herding cats is difficult but that challenge pales when compared with what was
attempted by the group of pulmonologists and pulmonary radiologists who combined to …

Chronic obstructive pulmonary disease (COPD) is a complex genetic disorder in which
environmental factors, such as tobacco smoke, interact with genetic susceptibility to cause …

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 …

In the current issue of the Canadian Respiratory Journal, Tulek et al (1)(pages 91-96)
examined the concept that high-resolution x-ray computed tomography (CT) measurements …

Background: Using CT to define phenotypic abnormalities in patients diagnosed as having
chronic obstructive pulmonary disease (COPD) may serve to optimize treatment, guide the …

Purpose: Quantitative CT (QCT) has the potential to identify three distinct components of
COPD: emphysema, air trapping, and airway wall thickening. Our hypothesis was that these …

To appreciate the value of CT imaging for routine care of patients with COPD it is best to start
by considering the limits of such technology. CT scanning provides exquisite in vivo …

Chronic obstructive pulmonary disease (COPD) is characterized by the presence of airflow
limitation that is caused by a combination of small airway remodeling and emphysema …

BACKGROUND: COPD patients have varying degrees of airways disease and emphysema.
CT scanning can differentiate these pathological subtypes. We evaluated airway dimensions …

Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease that is
characterized by chronic airflow limitation. Unraveling of this heterogeneity is challenging …
