Previously ultra-high dielectric constant (uHDC)
materials have shown to greatly improve proton MR
imaging at 3 T. In this study we are trying to explore
the potential of utilizing such materials in a sleeve
around the head to dramatically increase the
signal-to-noise ratio by more than 100 %. At the same
time we were able to cut the necessary transmit power
for a standard single voxel spectroscopy in half while
using the high dielectrics.
