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.
