Can someone help me with the meaning of my Ultrasound measurements?

Hi,

You haven't mentioned if you understand the abbreviations - but these are all different estimated fetal weight (EFW) estimation - either using biparietal or occipito-frontal diameter (BPD&OFD) or measuring head or abdominal circumference (AC&HC) and the femur bone's length (FL). Hadlock is the guy this measurement technique is named after.

There are always deviations from the 'normal' (in the statistical sense) measurement - as babies have different proportions. not to mention these are 'operator-dependant' (your baby might move and skew measurement).

So, to make a long story short, don't worry about a couple of days in each directions, that's what 'range' is for.

NB - not an obstetrician, knowledge from personal experience and general medical training.

CM means cisterna magna I do believe. If it is in millimeters. (measurement of a normal fluid pocket in the brain). Va I'm not too sure about. Could be the lateral ventricle measurement. Baby A has 2 measurements because the sonographer took 2 measurements to be more accurate, but I see the two are exactly the same. I hope everything is going well!

The ultrasound technician said everything was normal, but I just want to know what everything means. These are my baby girls measurements:

BDP(Hadlock) 4.36 cm--Age: 19w1d Range: 17w3d-20w6d Dev. 27.6%

OFD (HC) 6.30 cm

HC (Hadlock) 17.17 cm--Age: 19w5d Range: 18w2d-21w2d Dev. 43.8%
