Accuracy of 5D LB Ultrasound in Predicting Birth Weight of Preterm Fetuses : A Pilot Study

5D and 2D ultrasound will be done for pregnant women within 72hours before preterm delivery to determine estimated fetal weight by ultrasound. The estimated fetal weight by 5D and 2D ultrasound will be compared to the actual birth weight to determine accuracy of 5D ultrasound in predicting actual birth weight .
