Moving to ultra-high fields (≥7T), the inhomogeneity of both RF and static magnetic fields increases, which motivates to design a realistic head-shaped phantom. In this study, a 3D-printed head-shaped phantom with brain mimicking metabolites and lipid layer examined for 7T MRI and MRSI. The phantom was designed to resemble the brain with respect to B0 and B1 distributions, metabolites and lipid layer. We examined it for 1H MRS and MRSI, especially in the lipid layer vicinity. We also demonstrated in EPI that the Fat Suppression pulse flip angle can be optimized to minimize the lipid artifact and reduce the SAR.
