Figure 17. Axial CT slices, axial CALIPER-derived color image overlays, 3-dimensional (3D) CALIPER coronal rendering and Glyph of the lung parenchymal pattern as various colors (dark green = normal lung, light green = mild LAA, yellow = ground-glass opacity, orange = reticular pattern, brown = honeycombing). A, i–iiii, Imaging results of a 79-year-old male no smoker, with IPF. Mean visual scores of the CT: 20% reticulation, 15% honeycombing, no ground-glass opacity, fibrotic score 35%. CALIPER characterized 9% reticular pattern, 1% honeycombing, 20% ground-glass opacity, 5% Vessels, and 29% ILD. B, i-iiii Same patient after 1-year of follow-up without treatment. Mean visual scores of the CT: 25% reticulation, 20% honeycombing, no ground-glass opacity, fibrotic score 45%. CALIPER characterized 16% reticular pattern, 1% honeycombing, 34% ground-glass opacity, 8% Vessels and 51% ILD.

SECONDA TC23/03/2020
Si nota la riduzione di densità del consolidamento dovuto al COVID che nella prima TC appare arancione (retcolazione), mentre nella seconda maggioremente giallo (ground-glass)
PRIMA TC16/03/2020
SECONDA TC23/03/2020
Di nuovo si ossera la riduzione delle aree arancioni (retcolazione), che si «trasforma» in giallo (ground-glass)
