High-resolution computer tomography revealed centrilobular and panlobular emphysema
in the upper lobes and bilateral fibrotic changes in the basal segments of the lower lobes with sporadic honeycombing (Figures 3 and 4).
For calculation of accuracy there are four classes designed: normal tissue (NT), centrilobular emphysema (CLE), paraseptal emphysema (PSE), and panlobular emphysema
Other differentiating radiologic features from panlobular emphysema
include upper lobe predominance, greater degree of lung inflation, and less frequent bullous formation [64, 65].
The findings "extend earlier reports by showing that there is both widespread narrowing and loss of smaller conducting airways before the onset of emphysematous destruction in both centrilobular and panlobular emphysema
phenotypes of COPD," Mr.
