Understanding scan print out

[gallicgirl]

Hello all

I'm new to MN and hoping you can help me understand the print out from my scan. Had my 20 week scan today and all was well but there were a couple of things on the print out I didn't understand and it's ages til my next mid-wife appointment.

Under the biometry/anatomy section there's a list of abbreviations:

BPD
HC
AC
HC/AC

I have measurements in mm for the first three and a figure of 1.18 for HC/AC. There are also little graph type things next to the figures.

Could anyone shed any light on the abbreviations please?

They are measurements - Biparietal diameter, head circumference, abdominal circumference. If they were not in the normal range I'm sure the ultrasonographer would have informed you.

HC to AC is a ratio hence 1:18

Agree with EColi. The sonog would have said if they were worried

She wasn't worried at all and said everything was normal. I just wanted to know what they meant. I like to know everything!

Thank you so much for your prompt responses :)
