Computed tomography. (A). Representative example of one AdTGF-b1 exposed rat, scanned at day 0, 21, 35 and 56. Axial slice of CT-scan (upper panel) and 3D reconstructed lungs with fibrotic areas color-coded in green (medium panel). Corresponding histograms of total lung voxels from same animal (lower panel; insert represent percentage of fibrotic tissue. (B). Average percentage of voxels different from naïve lungs (All values are given as mean, SE, n = 4 to 6 at each time-point).
