    Hey, I went and got a babybond scan two weeks ago and well, they give me the handout with his measurements on them and they confuse me to hell. Can anyone help me and tell me what they mean? Also, this baby is a lot heavier than I remember my first being is it possible he's going to be big?

    Measurements

    His value is 324g(11oz)
    Range is +48g

    Growth
    under growth they have the word williams? So confused by that!

    HC
    Value - 175.0mm
    Dev - >95.0%

    AC
    Value - 153.01mm
    Dev - 93.5%

    FL

    I don't know, but this link does. https://www.brooksidepress.org/Prod...ound/2ndand3rdTrimesterUltrasoundScanning.htm

    Scroll about half way down.

    And what they mean:

    What are "AC", "BPD", "FL" and "HC" in ultrasound measurements?

    Abdominal Circumference (AC) measures the mother's belly in cross section. Especially later in pregnancy, it is used as an indicator of fetal weight and growth. Sometimes, serial measurements are taken to ensure an accurate reading.

    BPD stands for Biparietal Diameter and is an ultrasound measurement taken of the baby's head (from side to side). Along with the Femur Length (FL) and Abdominal Circumference (AC), it is used to estimate the fetal weight.

    Femur Length (FL) often is measured along with AC and BLD measurements. The femur is the longest bone in the body and measurement of this bone is taken to estimate fetal growth.

    AC, BPD and FL are combined in a formula to estimate fetal weight. While most ultrasound machines contain calculators, here is the formula used to figure the fetal weight: 1.4 X BPD X FL X AC (all in centimeters) - 200 = Fetal weight. (This is an estimate and becomes less accurate as baby gets farther from about 5.5 lbs.)

    HC indicates Head Circumference. Babies of the same weight can have different head sizes.
