First-trimester Placenta Volume and Three-dimensional Vascularization

Abstract

The relationship between placental size and its vascularization and perinatal pathology is well recognized. First-trimester assessment of placental volume and vascularization may predict birthweight and outcome of pregnancy. The size of the placenta can be determined by three-dimensional (3D) ultrasonography and by superimposing power Doppler (PD) its vascularization can be reliably reproduced. In this chapter, we will review the technique of obtaining placental volume and vascularization, the methodology of analysis of acquired volume, and their potential clinical applications.
