In situ 3D magnetic resonance spectroscopic imaging
(MRSI) was combined with focused-beam microwave
irradiation (FBMI) and multicoil (MC) shimming. MC
shimming has previously been shown to greatly improve
the magnetic field homogeneity in vivo. Similar
improvements were achieved on the FBMI samples as judged
from B0 maps and water 3D MRSI datasets. As a
demonstration of the improved data quality GABA-edited
3D MRSI was performed.
