Multiband (MB) techniques allows many thin slices in
conjunction with multi-echo within a given TR normally
used for conventional EPI of the whole brain. Summation
of contiguous thin slices with this technique recovered
signal drop-out from susceptibility artifacts and
improved BOLD sensitivity from these areas. This
technique can be routinely used for fMRI studies
focusing on areas with high susceptibility artifacts.
