The mean and SD for all subjects of the position of highest value density for white matter and gray matter observed in the 2D histogramsa
| WM | GM | Intercept | Slope | |
|---|---|---|---|---|
| R1 | 1.47 ± 0.08 s−1 | 1.27 ± 0.09 s−1 | 1.24 s−1 | 0.030 s−1/% |
| R2 | 12.55 ± 1.25 s−1 | 12.11 ± 1.08 s−1 | 12.06 s−1 | 0.066 s−1/% |
| PD | 52.01% ± 2.98% | 71.36% ± 3.95% | 73.46% | −2.85 %/% |
| Myelin | 30.98% ± 3.77% | 4.84% ± 2.30% | 2.01% | 3.84 %/% |
| LFB | 7.54% ± 2.06% | 0.74% ± 0.65% | – | – |
↵a Added are the derived slopes and intercepts when using the positions of R1, R2, PD, and myelin as a function of the position of LFB.
