Halsaka et al reported an equation for predicting birth weight of a term fetus using sonographic measurements. The authors are from the 2nd Medical Faculty of the Charles University in Prague.
Patient selection: healthy term pregnancy
(1) biparietal diameter in cm (BPD)
(2) abdominal circumference in cm (AC)
(3) femur length in cm (FL)
value of X =
= (0.64041 * (BPD)) - (0.03257 * ((BPD)^2)) + (0.00154 * (AC) * (FL))
estimated fetal weight in grams =
= 10 ^ (X)
