Is middle cerebral artery Doppler related to neonatal and 2-year infant outcome in early fetal growth restriction?

In a monitoring protocol based on ductus venosus and cardiotocography in early fetal growth restriction (26+0-31+6 weeks of gestation), the impact of middle cerebral artery Doppler and its ratios on outcome is modest and less marked than birthweight and delivery gestation. It is unlikely that middle cerebral artery Doppler and its ratios are informative in optimizing the timing of delivery in fetal growth restriction before 32 weeks of gestation. The umbilicocerebral ratio allows for a better differentiation in the abnormal range than the cerebroplacental ratio.
