The importance of the cerebro-placental ratio at term for predicting adverse perinatal outcomes in appropriate for gestational age fetuses.

Objectives: This study investigates the relationship between the cerebro-placental ratio (CPR) measured at 40+0 weeks' gestation and perinatal outcomes to determine a CPR cut-off that may justify induction of labor at term in appropriately grown fetuses (AGA). Although CPR is used for monitoring growth-restricted fetuses, its role in guiding labor induction decisions for AGA pregnancies at term remains unclear.

Methods: A retrospective cohort study was conducted using data from 491 singleton pregnancies with intended vaginal deliveries between 2015 and 2021.
