Comparing the relation between ultrasound‐estimated fetal weight and birthweight in cohort of small‐for‐gestational‐age fetuses

Abstract

Small-for-gestational-age infants with a birthweight <10th percentile are poorly identified antenatally with little improvement for those <5th percentile. In SGA babies, ultrasound EFW overestimated birthweight. Discrepancies between birthweight and EFW are not explicable only by the limitations of third-trimester sonography, a reduction in fetal weight close to delivery in a proportion of liveborn SGA babies is plausible.
