Doppler Ultrasound (US) is the standard clinical tools
used for evaluating fetal vessels. However, the efficacy
of these techniques is operator dependent and may be
difficult in certain cases. On the other hand, MRI is
ideally suited for vascular imaging. Fetal vascular
imaging is limited not only by the imaging resolution
but also by motion artifacts. In this study we evaluated
the feasibility of acquiring non-contrast enhanced
magnetic resonance angiographic (MRA) in the human fetus
and further, simulated a compressed sensing CS sampling
scheme to evaluate the potential utility of CS
reconstruction in fetal MR angiography.
