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.
