The conventional spectrally selective fat saturation pulse may perform poorly with inhomogeneous B0 and/or B1 fields at high fields, and the pulse length may be too long for low field applications. We investigated a 4D spectral-spatial fat sat pulse which mitigates the field inhomogeneity problem in fat sat and also largely reduces the pulse length.
