Ultrasound angiology reference standards of fetal cerebroplacental flow in normal Egyptian gestation: statistical analysis of one thousand observations

Doppler velocity assessment is the most frequently used method in clinical practice to identify fetal well-being, as it is considered as a non-invasive estimation of the fetus and feto-placental circulation. The aim of the current study is to establish longitudinal reference ranges for MCA and UA Doppler velocities, systolic-to-diastolic (S/D) ratio, resistive index (RI) and PI, and cerebroplacental ratio. The current study was a multicentric...
