The intrinsic B1 non-uniformities from standard volume resonators at high field are particularly problematic for localized spectroscopy of areas such as the temporal lobe, where low signal-to-noise results from a reduced B1 field. Using a recently developed high dielectric constant material placed around the head, increases in signal-to-noise of ~ 200% can be achieved in such problem areas without reducing the sensitivity in other areas of the brain.
