Figure 7.
The effects of diffusion-weighting scheme on GFA and crossing angle for four scan-time-equivalent sessions are shown as representative axial slices and as ROI-based analysis. The three separate scan sessions are represented as triangles, diamonds, and circles. Horizontal lines indicate the mean over three sessions of all data acquired per session, for the corresponding STE, ROI, and b-value. Note that axis limits are different across ROIs (while the scale remains the same). Results are shown for a b-value of 2,000 s/mm2, for results at all b-values, see Supplementary Figure 5. If no second fiber crossing is detected, no data point is shown.
