Figure 3:

Illustrative examples of sampled lung areas with ex vivo CT, micro-CT, and histologic staining. (A) Axial noncontrast ex vivo CT scan shows highly abnormal (25% healthy, 55% reticulation, 20% ground-glass opacification) lung findings. (B–E) Micro-CT scan (B) and histopathologic images (hematoxylin-eosin [C, D] and trichrome [E] staining; magnification, ×5 for C and E, ×20 for D) of the area highlighted with the circle in A show paraseptal and interstitial fibrotic changes. (F) Axial noncontrast ex vivo CT scan shows lung considered healthy (80%), with mild ground-glass opacification (15%) and limited reticulation (5%). (G–J) Micro-CT scan (G) and histopathologic images (hematoxylin-eosin [H, I] and trichrome [J] staining; magnification, ×5 for H and J, ×20 for I) of the matched location (circle in F) show paraseptal and interstitial fibrosis. Awy = airway, BV = blood vessel.
