Doppler sonographic quantification of placental perfusion with a new software based technique

Objective: Placental function depends on optimal perfusion. Here we present a new method – the PixelFlux-technique – a non-invasive automatic Power Doppler sonographic parenchymal perfusion measurement to quantify differences between perfusion from the maternal versus the fetal side of the placenta. Patients and methods: Power Doppler sonographic videos of anteriorly and centrally located placentae from 22 women with normal outcome of pregnancy at various gestational ages were recorded under defined conditions. Tissue perfusion intensity in four placental compartments was calculated as product of Doppler amplitu…
