FIGURE 5.

Volumetric 2D aMRI vs volumetric 3D aMRI. Anatomical reference (A), and maximum difference maps calculated from the original (unamplified) 3D cine data (B), volumetric 2D aMRI (C), and volumetric 3D aMRI (D). Volumetric 3D aMRI succeeded in capturing in‐ and out‐of‐plane motion, while significantly decreasing motion artifacts compared to volumetric 2D aMRI. This is well demonstrated in the region of the optic chiasm on the coronal image where brain motion is concentric as opposed to inferior/superior
