Imaging with fat suppression near metal-induced off-resonance has limited options due to the spectral ambiguity between fat and water. We propose Magnetization Transfer (MT) as an alternative for fat suppressed imaging near metal. We demonstrate that fat suppressed images can be efficiently obtained by modifying slice interleaving of conventional multispectral acquisitions that utilize fast spin echo readouts. These high RF power fast spin echo readouts act as MT preparation pulses for adjacent slices. Furthermore, we show that the image contrast can be predicted by Bloch simulations that incorporate the two-pool model and validate the simulations with in-vivo measurements.
