Non-contrast enhanced methods are needed to quantify placental perfusion to detect and monitor pathophysiological changes during pregnancy. We evaluate the potential of an endogenous perfusion labeling perfusion technique, Arterial Spin Labeled Flow-sensitive Alternating Inversion Recovery (ASL FAIR), and compare with ferumoxytol dynamic contrast enhanced (DCE) MRI. Three pregnant rhesus macaque were imaged with both FAIR and ferumoxytol DCE. Localized regions of ASL perfusion were observed that coincided with regions of early contrast enhancement seen in DCE. Ferumoxytol DCE measured perfusion with extended transit times across the placenta beyond those typically used for ASL labeling.
