Microvascular imaging of thick placenta with fetal growth restriction

Seven normal pregnancies at 11-34 weeks and three cases of a thick placenta with fetal growth restriction (FGR) at 19, 31, and 33 weeks were studied to assess placental vascularity using two-dimensional (2D)/three-dimensional (3D)-SMI (Aplio 800 or i900, Toshiba Medical Systems, Tokyo, Japan).
