Initial fMRI studies of the fetal brain have used
standard multi-slice 2D EPI sequences and either
required intra-volume motion correction or led to a high
data rejection rate. We propose combining an EVI readout
with localized excitation of the fetal brain to achieve
a TR in the order of 150ms therefore significantly
reducing sensitivity to motion. This methodology was
shown to be feasible in three adult volunteers and a
first acquisition test was performed on the fetal brain
in utero.
