of airway dimensions by CT would provide additive value to the measurement of emphysema …

… Current and ex-smokers with a clinical diagnosis of COPD were recruited from primary
care and through a respiratory outpatient clinic at the Royal Infirmary of Edinburgh. Chronic …

… In CT scans of smokers with COPD, the subsegmental airway wall area percent (WA%) is …
the segmental airways. Because emphysema is linked to loss of airway tethering and may limit …

… The aims of this study are to quantify airway dimensions of the lung in multipleairway sections
of each lobe in a novel manner and the extent of emphysema by usinglow-dose CT. These …

… in the resected tissue most severely affected by emphysema. It is unknown whether sex
differences in airway dimensions exist in areas of lung less severely affected by emphysema. …

… To our knowledge, we are the first to describe sex differences in CT measurements of airway
dimensions. Our findings contradict the histological results in a subgroup of 101 subjects …

… Thus, we cannot fully evaluate the effects of smoking per se on airway dimensions. Additionally,
a fundamental limitation of airway measurements is the spatial resolution (voxel size: x, y…
