Placental Versus Cerebral Doppler Parameters in Early‐Onset and Late‐Onset Fetal Growth Restriction

MCA DDA was not independently associated with FGR or CANOs in either EO-FGR or LO-FGR. In contrast, placental Doppler parameters, particularly UA PI and CPR, showed stronger and independent associations with FGR, reinforcing their central role in clinical evaluation. CANOs were multifactorial and not independently linked to any Doppler parameter. Further studies are needed to validate the clinical utility of MCA DDA.
