Functional imaging of the nonhuman primate Placenta with endogenous blood oxygen level–dependent contrast

Abstract

Maternal spiral arteries show strong spatial correlation with foci of extended T2* observed in the primate placenta. A simple model of oxygen transport accurately describes the spatial dependence of R2* within placental lobules and enables assessment of placental function and oxygenation without requiring administration of an exogenous contrast reagent.
