High-field X-nuclei MRS for human application at
high/ultrahigh field often suffers from high SAR,
limited SNR and long scanning time. In this report, we
demonstrate that more than 130% SNR gain was achieved
with ultra high dielectric constant (uHDC) materials
incorporated into the RF coil for 31P MRS and CSI at 7T.
Concomitantly, the RF power optimized for acquiring the
spectra was reduce by 43% with the uHDC material. Our
results suggest that uHDC material can be incorporated
into the RF coil for high-field X-nuclear MRS to
significantly improve SNR and reduce transmission power.
