PMID:29456581 57. Milner J, Arezina J.The accuracy of ultrasound estimation of fetal weight in comparison to birth weight: A systematic review.Ultrasound. Conclusion Clinical estimation of birth weight in early labor is as accurate as routine ultrasonic estimation obtained in the preceding week. Ultrasound Obstet Gynaecol 2014 ; 44: 210 – 220 . In the birth weight greater than 4000 g, both methods underestimated the birth weight, and the mean errors and the rate of estimates within 10% of birth weight were similar for both methods. Ultrasound measurements of the fetus's head, abdomen, and upper thighbone provide a more accurate way to determine size. Baby was born on 12/13 at a shocking tiny 6lbs 5oz! Comparison of conventional 2D ultrasound to magnetic resonance imaging for prenatal estimation of birthweight in twin pregnancy Caroline Kadji, Elisa Bevilacqua, Ivan Hurtado, Andrew Carlin, Mieke M Cannie , Jacques C Jani Khalil, A, D’Antonio, F, Cooper, D Ultrasound estimation of birth weight in twin pregnancy: comparison of biometry algorithms in the STORK multiple pregnancy cohort. My ultrasound said 9 lbs but tech said give or take 1 lb. 2012;10(38):74-6. There was positive correlation between the ultrasound estimated weight and the actual birth weight. Accuracy of fetal weight estimation is of key importance in antenatal care, as well as in the planning and management of labour and mode of delivery [1,2,3,4,5,6,7,8,9].In order to achieve more accurate prenatal fetal weight estimations and align these with a risk-optimizing mode of delivery, additional tools supporting the standard of use with ultrasound are needed. Bajracharya J, Shrestha NS, Karki C. Accuracy of prediction of birth weight by fetal ultrasound. I didn't have an ultrasound for weight done, but my midwife felt my belly and said 'whoa thats going to be a big baby!' I carried a 9 lb baby and I just don’t feel like this one is as big.

Background The aim of the study was to evaluate the ultrasound-derived measurements of the fetal soft-tissue, heart, liver and umbilical cord in pregnancies complicated by gestational (GDM) and type 1 diabetes mellitus (T1DM), and further to assess their applicability in the estimation of the fetal birth-weight and prediction of fetal macrosomia. PMID: 23132481 The mean birth weight was 3.47 kg ± 0.47, while the mean estimated ultrasound weight was 3.43 kg ± 0.8. At 36 weeks she was predicting she was over 7lbs and if I went to 40 she would be 8/9 lbs. The mean ultrasound scan to delivery … After knowing the answer to "how accurate are ultrasounds for weight", you may wonder how the weight is measured with ultrasound. In a 2009 study out of Texas, moms who had a baby with birth weight overestimated by 15 percent before labor, had a greater chance of C-section delivery. There is no method of checking fetal size before delivery can provide more than an estimated fetal weight (EFW). But unlike weighing the baby on a scale after birth, even the best ultrasound measurements aren't 100% reliable. Mean birth weight in the cohort was significantly lower (2963 vs 3306 g, P < 0.001) than that in the state. Kathmandu Univ Med J (KUMJ) .
