Suppression of extra cranial
lipid signals is a significant challenge for MR
spectroscopy at high field. This study describes the use
of a crusher coil in a volumetric proton echo-planar spectroscopic imaging (EPSI)
sequence for 7T. It is shown in vivo
that the application of the crusher coil improves the spin-echo 7T EPSI
sequence and allows to record high quality spectroscopic imaging data with
extended 3D coverage and low RF power deposition.
