FIG. 6.

Results from volunteer 6 for the 13-dir acquisitions at 500 and 250 μm radial resolution. The top panel shows MPRAGE data resampled into the same orientation as the line-scan acquisitions, with the prescribed line overlaid in yellow and the yellow circle indicating the origin in the plots below. Plots of FA and radiality index versus position along the line are shown in black and purple, respectively, for the 500 μm (middle panel) and 250 μm (bottom panel) acquisitions. Note that the radiality index is only defined for gray matter voxels with FA ≥ 0.05.
