| Intercept | Slope | Spearman ρ | |
|---|---|---|---|
| R1 | 1.19 ± 0.10 s−1 | 0.065 ± 0.009 s−1/% | 0.63 ± 0.12 |
| R2 | 12.31 ± 1.17 s−1 | 0.044 ± 0.131 s−1/% | 0.11 ± 0.28 |
| PD | 71.96 ± 4.22% | −2.45 ± 0.53 %/% | −0.73 ± 0.09 |
| Myelin | 1.50% ± 2.84% | 4.37% ± 1.73 %/% | 0.74% ± 0.11 |
↵a Estimated by linear regression and the Spearman ρ of the LFB optical density as a function of (uncorrected) R1 and R2 relaxation, proton density, and (temperature-corrected) MRI-estimated myelin partial volume.
