Background: The smaller airways,< 2 mm in diameter, offer little resistance in normal lungs,
but become the major site of obstruction in chronic obstructive pulmonary disease (COPD) …

Chronic obstructive pulmonary disease (COPD) is divided into pulmonary emphysema and
chronic bronchitis (CB). Emphysema is defined patho-anatomically as “permanent …

Multidetector computed tomography (MDCT) acquisition during a single breath hold using
thin collimation provides high resolution volumetric data set permitting multiplanar and three …

With advances in multidetector-row computed tomography (MDCT), it is now possible to
image the lung in 10 s or less and accurately extract the lungs, lobes, and airway tree to the …

Quantitative assessment of airway-wall dimensions by computed tomography (CT) has
proven to be a marker of airway-wall remodelling in chronic obstructive pulmonary disease …

Background COPD is a heterogeneous disease characterized by airflow obstruction and
diagnosed by lung function. CT imaging is emerging as an important, noninvasive tool in …

Rationale: Pulmonary hypertension (PH) is an established complication of advanced chronic
obstructive pulmonary disease (COPD) associated with increased mortality. The …

PURPOSE: To prospectively evaluate airway wall thickness and lung attenuation at
spirometrically gated thin-section computed tomography (CT) in patients with chronic …

Alterations in the structure of the airways, collectively termed airway remodelling, contribute
to airflow obstruction in a variety of chronic lung diseases. While histology has provided …

Chronic obstructive pulmonary disease (COPD) is characterized by the presence of airflow
obstruction caused by emphysema or airway narrowing, or both. Low attenuation areas …
