What is the normal CRL at 12 weeks in mm?

The accuracy is approximately 75% between 50-55 mm, or 11+4 weeks to 12 weeks of gestation, but increases to 96% with a CRL of 55-60 mm. For male fetuses, in fact, it is 99% vs 93.5% in females at this time. As stated above, by 12+2 weeks, with a CRL of 60 mm or more, the accuracy is 100% for both sexes.

What is CRL for boy vs girl?

Conclusions: When CRL ≥ 60 mm (gestational age ≥ 12+2), fetal gender can be accurately ascertained. Male gender may already be reliably determined when CRL ≥ 55 mm (gestational age ≥ 12+0). If CRL < 50 mm (gestational age < 11+4) the gender cannot be reliably predicted.

If the CRL is 55 mm, what is the fetus's gestational age?

A fetus's gestational age is calculated to be 12 weeks and 1 day if its crown-rump length is 55 mm. The given gestational age is calculated according to the corrected Robinson and Fleming equation, which has been ranked among the four most accurate fetal assessment equations.

What is CRL on ultrasound?

The measurement made from an embryo's or fetus's top head to its buttocks is called the crown-rump length (CRL). CRL is typically determined through ultrasound and helps determine gestational age in early pregnancy.
