In fMRI, image acquisition and processing are typically
treated as separate processes. We show here that when
the goal is to obtain the functional time course of
brain networks or nodes, the SNR per unit time can be
dramatically increased by collecting highly under
sampled data and estimating the time courses directly
from raw k-space data, bypassing the formation of
conventional images.
