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.
