Recently we have implemented a multiband (MB) multi-echo
(ME) sequence to investigate the potential improvement
in sensitivity at 7T for resting state (RS) fMRI. In
this study we investigated various approaches for
cleaning ME and MB ME RS fMRI data to fully exploit the
rich temporal information of MB ME data. With two
different analysis strategies we have showed that MB
acquisition improves functional connectivity compared a
standard ME sequence after the removal of non-BOLD
related artifactual signals.
