The
fast spectroscopic imaging method spectroscopic RARE was implemented on a
7-Tesla animal scanner and applied to rat brain in vivo. It is shown that
various experimental problems occurring at higher B0 can be eliminated
and, compared to earlier results at 4.7 T, the potential of a higher
signal-to-noise ratio and increased spectral resolution can be exploited. As
increased spectral resolution requires a larger number of kΩ
-encoding steps and thus a longer minimum total measurement time, the use of
phase corrected spectra calculated from asymmetric kΩ
-sampling is considered as an alternative to magnitude spectra calculated
from symmetrically sampled kΩ -data.
