Cerebroplacental ratio
Cerebroplacental ratio is a tool used in obstetric ultrasound to predict adverse pregnancy outcome.[1] It is measured by dividing the pulsatility index of the middle cerebral artery of the foetus by the pulsatility index of the umbilical artery of the foetus. A cerebroplacental ratio lower than 1-1.1 in uncomplicated pregnancies is indicative of placental insufficiency, independent of the actual fetal size.[2][3]
