BABY WEIGHT OF CONTENTS (EFW) COMPATIBLE WITH AGE? (BPD, HC, AC, FL)

What is BPD, HC, AC & FL in ultrasound? Does the baby weight (EFW) age-appropriate content?

• In the first trimester, infant development assessment by calculation sac in the uterus (gestational sac, GS) or fetal length is calculated from the apex of the head to the buttocks, (Crump rump length, CRL). Expected date of birth (Estimated due date, EDD) your baby can be calculated by measuring the CRL.
• After the first trimester of pregnancy, the assessment for the expansion content multiparameter baby through fetal biometry measurements. This should include at least two fetal measurements (usually biparietal diameter (BPD) and femur length (FL)) plus consideration of additional parameters such as head circumference (HC), abdominal circumference (AC).
• All measurements are related to gestational age, it is not always important how fetal biometry parameters are combined to estimate the baby's weight. Most modern ultrasound machines including program analysis for fetal biometry used to calculate the term infant birth date (EDD) and the term baby's weight (EFW).


GS (Gestational sac)

• Taken in week 5 and week 6
CRL (Crump-rump length)
• The length of the head to the dorsal apex. Taken at week-6 and week-12.
BPD (Bi-parietal diameter)
• Width across the baby's head. Taken at week-13 and week-40.
HC (Head circumference)
• The distance around the circumference of the baby's head. Taken at week-13 and week-40.
AC (abdominal circumference)
• The distance around the circumference of the abdomen / stomach baby. Taken at week-13 and week-40.
FL (femur length)
• The length of the femur. Taken at week-13 and week-40.
EFW (Estimated fetal weight)
• Approximate weight of the unborn child through the calculation of BPD; HC AC, FL on ultrasound scan. It only estimate the baby's weight at the time of ultrasound does not predict your baby's birth weight.
