A placenta can be visualized as the echogenic material superior to the fetuses and the hyperechoic umbilical cord can be visualized in the center of the gestational sac. Pregnancies with monoamniotic twins are rare - about one in every 10,000 pregnancies is affected, or about 1 per cent of all incidences of identical twins. Separate amniotic sacs prevent the umbilical cords from wrapping around the babies, but there is a risk of Twin to Twin Tranfusion Syndrome, where one baby takes most of the nourishment resulting in drastic growth difference.
