Color Doppler images show blood vessel connections on the placenta.
Amniotic fluid volume alters imaging. The large baby on the left (recipient) has increased amniotic fluid, so a clear profile and clear imaging are obtained. The donor, on the right, is tightly wrapped in his membrane and imaging is very indistinct.
