The sensitivity of multiband separation to changes in the relative phase between simultaneously acquired slices is demonstrated. A phase estimation procedure is proposed and tested for a diffusion weighted acquisition. With a phase-updating strategy reduced signal fluctuations allows for improved detectability.
