A matrix-based framework for modelling of inhomogeneous MT effects was developed for steady-state gradient echo sequences. This was applied to sequences using multi-band pulses that are designed to create some off-resonance saturation simultaneously with excitation of free water. Simulations and phantom results show that ihMT contrast can be achieved in this way, and in-vivo results show the expected strong white-matter contrast.
