Prediction of early‐ and late‐onset pregnancy‐induced hypertension using placental volume on three‐dimensional ultrasound and uterine artery Doppler

ABSTRACT Objectives To determine whether uterine artery (UtA) Doppler findings and three‐dimensional (3D) ultrasound measurement of placental volume during the first trimester allowed prediction of early‐ and late‐onset pregnancy‐induced hypertension (early PIH and late PIH). Methods Subjects with singleton pregnancy who underwent an ultrasound scan at 11–13 weeks' gestation and delivered between 2011 and 2013 were enrolled prospectively into the study. The UtA Doppler indices and placental volume on 3D ultrasound at 11–13 weeks' gestation in cases that developed early PIH (
