Single ultrasonic estimation of fetal weight in utero compared with birth weight
A single ultrasonic determination of fetal weight in utero was made in 270 singleton pregnancies. Infants were divided by birth weights into two groups, less than and greater than the 50th percentile. Ultrasonically determined fetal weight correlated with birth weight (R2 greater than or equal to 0.52) beyond 33 weeks' gestation. Mean fetal weights measured by ultrasound at various stages of gestation correlated well with published values.
