In-vivo 31 P chemical shift imaging sensitivity improvement utilizing high dielectric pads

31P spectroscopy and imaging benefit greatly from ultrahigh field MRI. However, voxel sizes are typically still quite large and the low phosphorus metabolite concentrations require long acquisition times. In previous work it has been demonstrated that the image signal-to-noise ratio (SNR) can be improved by using high dielectric pads. This work has mainly focused on in vivo 1H imaging at 3 T and 7 T. Here, we show the first in vivo results of 31P CSI with improved SNR with a dielectric pad with an intermediate relative permittivity of ~300 (BaTiO3).
