Three-dimensional Sonoembryology

Abstract: Three-dimensional ultrasound is advantageous in studying normal embryonic and fetal development, as well as providing information for families at risk for specific congenital anomalies by confirming normality. The introduction of high-frequency transvaginal transducers has resulted in remarkable progress in ultrasonographic visualization of early embryos and fetuses. Three-dimensional ultrasound imaging in vivo compliments pathologic and histologic evaluation of the developing embryo, giving rise to a new term: 3D sono-embryology
