This work shows preliminary results demonstrating the
feasibility and potential for reducing the readout
length of the HASTE acquisition for 3T fetal imaging
while keeping the original voxel sizes, by applying
outer volume skewed saturation pulses oriented
perpendicular to the PE direction. Further optimization
of the application of spatial saturation pulses in the
pregnant abdomen is yet to be done. We believe that
these methods are promising way to reduce the HASTE
readout length and thus will make the HASTE acquisitions
less susceptible to fetal motion in the future.
