Abstract
Ultra-high-field (≥7T) MRI suffers from poor transmit (B₁⁺) homogeneity, particularly in neuroimaging. This study evaluated paired metasurfaces near the temporal lobes in five healthy volunteers versus dielectric pads and reference scans. Metasurfaces markedly improved SNR across the brain (FLAIR: ~24%, MPRAGE: ~97%) and in the temporal lobes (FLAIR: ~57%, MPRAGE: ~212%), also recovering signal in the cerebellum and neck. Simulations indicated a 23.5% increase in peak SAR compared to reference.
