[Ultrasonographic estimation of fetal weight in intrauterine growth retardation. Comparative analysis of 4 formula].
The accuracy of estimated fetal wight determined by US scan in 70 fetuses with IUGR was analyzed using different formulas. The formula used in our Service showed the best correlation between estimated fetal weight and birth weight (R = 0.92), with estimation error not significant and +/- 8.3% variability. The foreign formulas showed significant estimation error and over 10% variability, therefore, in our population the use of the local formula is recommended.
