Multi-echo and multi-band techniques have independently
and rapidly established themselves as new standards in
fMRI acquisition. Bringing them together offers
tremendous potential to reap the benefit of both: faster
TR to better resolve confounding physiological noise
such as heart beats, and the multi-echo information to
then separate out these signals. We evaluate different
combinations of slice- and in-plane acceleration with
different numbers of echoes in conjunction with
multi-echo denoising using ME-ICA.
