(A) Whole brain signal-to-noise ratio (SNR). (B) Third crossing fiber ratio in white matter (threshold at volume fraction 0.05). Primary imaging parameters were: RIKEN (N=20), MtS-P (N=4), UC-Davis (N=8) and YA-HCP (N=20): voxel size 0.7, 1.0, 0.7 and 2 mm3; number of directions (512, 60, 121 and 256) and b-values (0, 1000, 2000 and 3000; 0 and 1000; 0 and 1600; 0, 1000, 2000 and 3000 s/mm2), respectively. RIKEN data was obtained using HCP-style image acquisition protocols.
