In the current abstract we explore the applications of Multiband Echo-SHifted (MESH) EPI as a potential tool for fMRI at 3T. We compare MESH and SMS-EPI in two sets of experiments: the first looking into typical fMRI protocols, and the second with a focus in BOLD contrast and temporal resolution optimization. We conclude that MESH can increase the temporal efficiency of fMRI and be used to reduce distortions without sacrificing BOLD contrast.
