In vivo imaging of uterine artery blood flow during remodeling is potentially valuable in assessing placental function during pregnancy. We present 4D flow MRI of the uterine arteries, demonstrating inter- and intrasubject heterogeneity in vessel anatomy and hemodynamics. This high spatial resolution, multi-location approach potentially addresses the limitations of Doppler ultrasound in quantifying pulsatility and resistance indices as clinical biomarkers of placental health.
