# What does FL HC and AC mean?

## What does FL HC and AC mean?

Ultrasound measurements of biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC) and femur length (FL) are used to evaluate fetal growth and estimate fetal weight.

## What is the average femur length at 28 weeks?

The median femur diaphysis length ranged from 18.05 mm at 15 menstrual weeks to 52.20 mm at 28 menstrual weeks, and the mean humerus diaphysis length ranged from 17.65 mm at 15 menstrual weeks to 48.10 mm at 28 menstrual weeks.

What does HL stand for in fetal ultrasound?

Fetal ultrasound measurements can include the crown-rump length (CRL), biparietal diameter (BPD), femur length (FL), head circumference (HC), occipitofrontal diameter (OFD), abdominal circumference (AC), and humerus length (HL), as well as calculation of the estimated fetal weight (EFW).

### How can I increase my fetal femur length?

Amongst a mass of evidence in literature, only Chang et al. (14) established the role of milk on growth of femur length of foetus, showing that higher milk intake is related to better growth of femur length of foetus.

What is normal OFD in pregnancy?

The biparietal diameter measurement increases from roughly 2.4 centimeters at 13 weeks to approximately 9.5 centimeters when a fetus is at term.

Is BPD or HC more important?

Conclusion: Provided that the expected pregnancy duration was 282 days, both HC and BPD predicted spontaneous birth with a mean accuracy of one day, HC being significantly better than BPD.

#### What is AC of fetus?

AC (abdominal circumference), the length going around your baby’s belly. FL (femur length), the length of a bone in your baby’s leg.

#### What is the normal BPD at 20 weeks in CM?

Mean BPD showed an increase of 2.38 cm in 13-20 weeks, 2.18 cm between 20 and 27 weeks and only 1.72 cm from 27 to 34 weeks. Average growth rate of BPD was found to be 0.31 cm/week from 13 to 28 week, which then later reduced to 0.23 cm/week from 28 to 36 weeks of gestation.
