Ultrasonography plays an essential role in fetal surveillance. In early onset preeclampsia serial monitoring of fetal biometric parameters is required. Trends in fetal development are more significant than the actual size of the fetus. Serial measurements determining amniotic fluid index is pivotal, if preeclampsia is associated with fetal growth restriction. Ultrasound placental morphology does not correlate with severity in all preeclamptic cases. In addition to biophysical profile examinations; blood flow in fetal vessels and uteroplacental arteries provide valuable information on fetal well-being. Abnormal blood flow of the uterine artery primarily indicates risk of early onset preeclampsia associated with fetal growth restriction. Color Doppler ultrasonography of the uterine artery is an effective screening test to predict preeclampsia in a high-risk patient group. However, in the low-risk group due to the low positive predictive value it is not recommended.
