A multiband spectroscopic imaging acquisition is
described and applied at 3T. This method acquires
simultaneous multi-slice spectroscopic images with
minimal chemical shift dispersion error by virtue of a
cascaded excitation spin echo sequence. The phase
toggling of the excitation pulses creates an RF based
k-space separation of the individual slices that can be
spatially reconstructed by virtue of the sensitivity of
the receive array. In conjunction with a non-selective
inversion recovery, this method enables detection of
abnormalities in metabolites at the cortical edge. This
method is demonstrated in control and neurological
patients at 3T.
