Comparing the notch index and the notch depth index in the prediction of placental disorders

Abstract

Uterine artery (UtA) doppler can assist in the prediction of placental disorders such as hypertensive disorders in pregnancy (HDP) and fetal growth restriction. While the pulsatility index (PI), resistance index (RI), and the presence or absence of a diastolic notch (DN) where studied, little attention was given to attempts to quantify the DN. We aimed assign a numerical values to the DN in an attempt to provide a better prediction model for placental disorders.
