FIGURE 4.

PUSHUP‐WB CEST maps (semisolid magnetization transfer (ssMT), relayed nuclear Overhauser effect (rNOE), amide, amine from left to right) of one subject using the four ${\mathrm{B}}_1$‐correction methods (no correction, 1‐point correction, 2‐point correction, 3‐point correction from top to bottom). In the right column, corresponding slices from the MPRAGE, the motion correction reference, the segmentation and the normalized ${\mathrm{B}}_1^{\text{rms}}$ map are shown. The red arrows point to quantification artifacts. Red arrows point to regions with quantification artifacts. White arrows point to successfully corrected artifacts.
