Abstract

Prediction of twin birth weight discordancy was tested in 116 gestations using sonographic measurements of biparietal diameter (BPD) and abdominal perimeter. Abdominal perimeter measurement differences of 20 mm or greater were more sensitive and specific than BPD difference in detecting twins with dissimilar birth weights.
