New fetal weight estimation models using fractional limb volume

Comparison of three clinical and three ultrasonic equations in predicting fetal birth weight

“…22,23 Though not validated recent studies done using 3,4 D USG measuring foetal thigh measurements are showing significant accuracy in macrosomic baby MRI is another costly alternative which cannot be freely used routinely. 24 Among the measures of accuracy used in our study simple error was not a good predictor of accuracy and was misleading as because it is a sum of over and underestimates. In contrast absolute error and percentage error and weight within 10% are better indicator of accuracy as they represent variability regardless of direction.…”

Prenatal Detection and Consequences of Fetal Macrosomia

“…It is argued that, in comparison to conventional biometric formulae for estimated fetal weight, the addition of the degree of soft tissue provides no additional benefit for antenatal macrosomia detection [40]. Conversely, Lee et al [41,42] recently showed that the precision of fetal weight estimation improved following addition of fractional limb volume measurements to conventional two-dimensional biometry; the percentage of neonatal body fat was highly correlated with fractional thigh volume during the late third trimester.…”

3D and 2D ultrasound-based fetal weight estimation: a single center experience

“…However, even with these methods, the addition of AC to the new formulae, allowed better estimation of fetal weight than with the exclusion of AC. Although this appears to be a drawback, yet the performance of these methods was higher than the Hadlock formula [11].…”
