WM and GM SNRs of each shell
| shell | 0 | 1st | 2nd | 3rd | 4th | 5th |
|---|---|---|---|---|---|---|
| b value (s/mm2) | 0 | 375 | 1500 | 3375 | 6000 | 9375 |
| WM SNR | 22.65 ± 5.92 | 17.67 ± 4.13 | 9.01 ± 2.00 | 5.02 ± 1.20 | 3.57 ± 0.90 | 2.85 ± 0.71 |
| GM SNR | 29.33 ± 11.25 | 21.26 ± 6.38 | 9.09 ± 2.40 | 3.38 ± 0.82 | 1.88 ± 0.44 | 1.58 ± 0.32 |
Whole brain WM and GM were segmented by input Po map to FAST algorithm.
The standard deviation was calculated across whole brain ROI.
