If you a sonographer, do you use Robinson, Hadlock or other curves to estimate CRL?

Just curious - I am a bit of a geek when it comes to medical science and often go into a bit of a rabbit hole!

I've been reading about the Robinson and Hadlock curves, but also about the Pexsters paper from 2010 which proposed a new equation.

I'm interested as to which curve the NHS (or indeed, private practices) uses to estimate gestation from CRL?

Yours thankfully!

I'm sure there is someone on MN who can answer this!

All of my NHS baby scans have had Hadlock written on them if that helps OP.

It helps hugely! You’re a legend! Thank you @MeinKraft 🤩

@CanAnyoneSmellGarlic I live in another country in Europe - all baby scans say hadlock as well'
