Figure 4.

A, The comparison of uncorrected (isolated from Figure 3A), the linear model B ₁‐corrected (isolated from Figure 3A with the subsequent linear B ₁ correction), and the BE B ₁‐corrected (isolated from Figure 3B) MTR_Rex,amide effect size as a function of B ₁. B, The same as A but for MTR_Rex,NOE effect size. For the linear B ₁ correction, a B ₁ of 0.43 μT was assumed to be nominal B ₁ (100%). All other B ₁ levels were translated to percentages accordingly. The straight colored lines represent the linear regression relation between the corresponding metrics and B ₁. The Pearson correlation coefficient (R) is shown in each subfigure.
