Assessment of fetal weight based on ultrasonic femur length after the second trimester

Abstract

This simple, new and accurate equation appears to be clinically reliable and easy to use and suggests that previous normal ultrasonic fetal femur length curves for another population may underestimate or overestimate normal fetal weight for the Iranian population. Thus, our formula is an excellent means to estimate true fetal weight.

Can the growth factors PTHrP, Ihh and VEGF, together regulate the development of a long bone?

“…The growth plate remained stable, resulting in continuous, linear bone growth throughout the whole simulation period (48 weeks, 16 weeks after birth). The total bone growth rate as well as the number of cells predicted by the model corresponded to literature values (Chitty and Altman, 2002;Honarvar et al, 2001;Neufeld et al, 2004). Hence, we conclude that the growth factors PTHrP, Ihh and VEGF together could regulate linear growth in a long bone.…”

Ultrasound estimation of birth weight in twin pregnancy: comparison of biometry algorithms in the STORK multiple pregnancy cohort

“…The BPD, HC, AC and FL were measured according to a standard protocol. Estimates of fetal weight were calculated using the formulae listed in Table S1. These formulae utilize one or more of the abovementioned fetal biometric measurements to calculate fetal weight.…”

Relationship between fetal biometric assessment by ultrasonography and neonatal lamb vitality, birth weight and growth

“…For such analysis, the measurement of the length of metacarpus and the biparietal diameter are necessary, since they are considered bones of different allometric growth and high correlation with gestational age. Additionally, the femur length is considered a sensitive and accurate variable to estimate fetal growth and development (Honarvar et al, 2001).…”
