We present the feasibility of measuring and quantifying placental blood flow in healthy pregnant subjects at 1.5T. We used a Flow Alternating Inverson Recovery (FAIR) scheme with background suppression. Using statistical parametric mapping, discrete regions of labeling were observed, likely corresponding to individual spiral artery distributions.
