Abstract

Simultaneous multi-slice (multiband) fMRI is a novel acceleration technique that allows for dramatically improved spatiotemporal resolution. However, BOLD signal artifacts due to motion remain a critical confound in studies of functional connectivity that must be addressed to produce reliable and reproducible findings in psychiatric neuroimaging. While volume censoring of high-motion volumes (scrubbing) is an effective technique, empirically-validated bases for determining optimal censoring thresholds are unclear, particularly in multiband fMRI.
