Background Partial volume averaging and tilt relative to the scan plane on transverse
images limit the accuracy of airway wall thickness measurements on CT scan, confounding …

PURPOSE: To design and validate a dedicated software tool to measure airway dimensions
on thin-section computed tomographic (CT) images and to use the tool to prospectively …

Background Increased airway wall thickness (AWT) and parenchymal lung destruction
bothcontribute to airflow limitation. Advances in computed tomography (CT) post-processing …

Background In CT scans of smokers with COPD, the subsegmental airway wall area percent
(WA%) is greater and more strongly correlated with FEV 1% predicted than WA% obtained …

Background: Chronic obstructive pulmonary disease (COPD) is characterized by airflow
obstruction caused by emphysema or airway narrowing, or both. Recently airway …

Objective We reduced the computed tomography (CT)–reconstructed field of view (FOV),
increasing pixel density across airway structures and reducing partial volume effects, to …

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

Background It is time-consuming to obtain the square root of airway wall area of the
hypothetical airway with an internal perimeter of 10 mm (√ Aaw at Pi10), a comparable …

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 To prospectively apply an automated, quantitative three-dimensional approach
to imaging and airway analysis to assess airway remodeling in asthma patients. Methods …
