Benjamin M. Yeh: Has the Time Arrived to Image Placental Perfusion?
Taillieu et al have shown that it is possible to noninvasively measure the placental blood flow, fractional volume of the maternal vascular placental compartment, and rate of transfer of contrast material between the maternal and fetal circulation in gravid mice through the use of dynamic contrast-enhanced MR imaging.
