Root-flipped multiband pulses have peculiar spin-echo behaviour due to their non-linear phase profile. In spin-echo sequences, different slices will typically have different relaxation weightings. This work investigates the typical time-delays of the spin-echoes such pulses, and proposes a novel root-flipping method to minimize differences in relaxation weighting.
