OBJECTIVES The purpose of this study was to test the hypothesis that a formula incorporating 3-dimensional (3D) fractional thigh volume would be superior to the conventional 2-dimensional (2D) formula of Hadlock et al (Am J Obstet Gynecol 1985; 151:333-337) for predicting birth weight and macrosomia. METHODS We conducted a prospective cohort study of pregnancies complicated by pregestational ...

Numerous growth curves and formulas have been developed to calculate estimated fetal weight (EFW) from prenatal ultrasound (US). The four-parameter Hadlock formula (head circumference (HC), biparietal diameter, abdominal (AC), femur length) remains the most commonly used in United States. two-parameter INTERGROWTH-21st (HC AC) was created provide a more comprehensive international standard usin...

Some have argued for the direct use of newborn growth curve to predict small gestational age (SGA) infants based on prenatal ultrasound estimated fetal weight (EFW). Our objective was compare Hadlock (GC) with Fenton (FC) in predicting SGA EFW. We performed a retrospective cohort study from 01/01/18 01/01/19 all ultrasounds 30+0 32+6 and 35+0 36+6 weeks single institution. Multifetal gestations...

INTRODUCTION Small for gestational age (SGA) is defined as birthweight below the tenth centile at a particular gestational week. Birthweight centiles for different populations are varied. Generic reference for fetal weight and birthweight that could be adapted to local populations was recently described. The purpose of this study was to validate the reference for birthweights adapted to the loc...

BACKGROUND As low birthweight (i.e., birthweight < 2500 g) is a major determinant of neonatal mortality and morbidity, the pre-delivery detection of low birthweight is clinically advantageous. This study was performed to determine whether ultrasound is suitable for use in primary screening to detect low birthweight newborns. METHODS The primary outcomes included sensitivity, specificity, and ...

OBJECTIVES We aimed to determine the accuracy of sonographic formulas for estimating birth weight in twin pregnancies. METHODS We conducted a retrospective cohort study of consecutive twin pregnancies undergoing sonography at within 1 week of delivery. Pregnancies were included if biometric measurements and birth weight were available and excluded if anomalies were present. Estimated fetal we...
