Summary

With ongoing evolution of advanced ultrasound diagnostic in prenatal care the trend is to detect potential fetal anomalies in the first trimester if possible. Complex knowledge of normal fetal anatomy, embryology and ultrasound anatomy is important to be able to identify subtle abnormalities. In this review we demonstrate the possibilities of ultrasound imaging of fetal brain at late first trimester and describe normal central nervous system development week by week. Original images are presented.

Key words:
central nervous system, first trimester, ultrasound diagnostic, normal fetal anatomy, embryology, ultrasound anatomy.
