Fetal Weight Estimation by Ultrasound: Comparison of 11 Different Formulae and Examiners with Differing Skill Levels

Abstract

Some regression formulae appear to be favourable within defined weight ranges. Accuracy of the formulae, however, is still unsatisfactory, and new formulae focusing on specific weight ranges (e. g., macrosomic fetuses) are needed. In addition, experience in obstetric ultrasound improves accuracy of fetal weight estimation.
