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 sonographic landmarks of developing embryonic and fetal CNS and also suggested 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.In the future, 2D as well as 3D fetal neurosonography will be used routinely in all pregnant patients to examine the developing brain, the same way we now examine other fetal organs and organ systems.
