Reproducibility of first trimester three-dimensional placental measurements

Our study demonstrate an excellent intra and inter-observer reproducibility for vascular indices and a good reproducibility of the evaluated Doppler indices with intra-CC higher than 0.90. PV and PQ were also reproducible most of all within the same observer. As a conclusion, first trimester tridimensional sonography is a reproducible tool for the systematic study of placental vascularization.
