In order to diagnose a deviation from what is normal, it is important to understand and recognize the developmental milestones of the normal brain, how it grows and matures, reaching its almost final anatomy at birth.This chapter presents the 2D and 3D ultrasound tools as well as the sonographic landmarks of the normal developing embryonic and fetal CNS and also suggests new ways to study it systematically.The introduction of TVS in fetal neurosonography adds an additional powerful tool to the diagnostic algorithm, increasing diagnostic precision in patients suspected of an anatomically abnormal fetal CNS.Unlike in our third edition, we have integrated the previously separate sections dealing with the 2D and the 3D fetal brain anatomy. We believe they are inseparable, and both are necessary to understand the development and pathologies of the fetal brain.
