The brain is growing rapidly and this results in the head growing faster than the rest of the body. The embryo has a large forehead, and the eyes and ears continue to develop.

Nov 2, 2014 · In such cases, GA can be estimated by ultrasound measurement of fetal crown–rump length (CRL) or head circumference at < 14 weeks' and ≥ 14 weeks' gestation, respectively 8. Between 9 and 13 weeks' gestation, linear growth evaluated by CRL is rapid and the SD is rather small, which means that GA can be estimated accurately. These methods should minimise potential systematic errors in dating associated with pooling data from different health institutions, and represent a model for standardising CRL measurement in future studies. Correct estimation of gestational age is essential for any study of ultrasound biometry and for everyday clinical practice.
