5D LB Ultrasound in Determination of Fetal Weight in Normal Pregnancy : A Pilot Study

Accuracy of Five Dimensional Ultrasound Long Bones Fetal Biometry (5DUS LB ) for Prediction of Fetal Weight Compared to Two Dimensional Ultrasound: a Pilot Study

5D and 2D ultrasound will be done to normal pregnant women between 37 to 42 weeks gestation and fetal weight will be estimated using the hadlock formula using biometry measured by both ultrasounds. Accuracy of 5D ultrasound in determining fetal weight will be determined.
