ABSTRACT
The recent development of ultrasound technology has resulted in remarkable progress in the visualization of early embryos and fetuses and in the development of sonoembryology. With the use of three-dimensional ultrasound, structural developments in the first 12 weeks of gestation can be assessed more objectively and reliably. The new technology allowed for the evolution of embryology from postmortem studies to the in vivo environment. The purpose of this review to illustrate the potential of sonography in the study of structural and functional early human development.
