spatial-spectral excitation and frequency-selective saturation with a
binomial-series RF pulse scheme were evaluated for application at high
field. Both methods yield separate
water- or lipid-selective images in a single acquisition. In most circumstances, the performance of
the binomial saturation approach proves to be more robust. A strategy is described for overcoming
unwanted artifacts arising from magnetic susceptibility mismatch in
small-animal imaging.
