MR spectroscopy at high field is expected to benefit
from improved signal-to-noise ratios and spectral
resolution, due to increased chemical shift dispersion
and reduced strong coupling effects. This study
describes the development of a volumetric proton
echo-planar spectroscopic imaging (EPSI) sequence for
7T. It is demonstrated in vivo that the spin-echo 7T
EPSI sequence can be used to record high quality
spectroscopic imaging data with extended 3D coverage and
low RF power deposition.
