Quantitative comparison of the differences in PDD angular uncertainty. These PDD uncertainty difference histograms represent the number of voxels where the one-/two-flip angle PDD estimates outperforms the other. Here, solid/dashed lines refer to the difference between the single (${\alpha }_{\text{low}}$/${\alpha }_{\text{high}}$) and the dual flip angle approach (${\alpha }_{\text{low}}+{\alpha }_{\text{high}}$) respectively. Blue lines indicate the number of voxels where the two-flip angle approach outperforms the single-flip angle, whereas the red lines display the opposite. A log scale is used on both the x- and y-axes.
