The use of a 2D-EPI ghost correction for Multiband
imaging with in-plane undersampling is proposed to
address residual ghosting prevalent in low b-value
diffusion images at ultra high fields. Integration with
the slice-GRAPPA algorithm is demonstrated, with the
computational effort only affecting the calibration of
