Lack of tapering was present (p=0.010) and larger diameters were demonstrated in lower lobes with bronchiectasis (p=0.010). MicroCT analysis of tissue cores showed similar reductions of tissue percentage, surface density and number of terminal bronchioles in both COPD groups compared to control lungs.Although terminal bronchioles were equally reduced in COPD lungs with and without bronchiectasis, significantly more large and small airways were found in COPD lungs with bronchiectasis.Although terminal bronchioles are equally reduced in COPD lungs with and without bronchiectasis, significantly more large and small airways are found in COPD lungs with bronchiectasis http://bit.ly/2YJ5kKs
