Maps of the DTI scalar parameters.
AD (a), RD (b), MD (c) and FA (d) for the orientations θ = 0° (left-hand side) and θ = 90° (right-hand side). ROI-averaged values 〈AD〉 (e), 〈RD〉 (f), 〈MD〉 (g) and 〈FA〉 (h) and the normalised standard deviations σAD/〈AD〉 (i), σRD/〈RD〉 (j), σMD/〈MD〉 (k) and σFA/〈FA〉 (l). The bulk 〈AD〉 is shown as a reference by the dashed, grey line (e). The ROIs contain 1300±200 voxels.
