Three-dimensional (3D) power Doppler ultrasound facilitates the evaluation
of fetal cardiac blood flow and peripheral vascular trees, fetal organ blood flow,
placental vasculature and blood flow, and maturation of the uterine cervix. With the
recent advances in 3D power Doppler ultrasound as well as quantitative 3D power
Doppler histogram analysis, quantitative and qualitative assessments of the
vascularization and blood flow of fetal organs, the placenta, and uterine cervix have
become feasible. This technique may assist in evaluation of the fetal cardiovascular
system and feto-placental function, and offer potential advantages relative to
conventional two-dimensional power Doppler ultrasound assessments. In this chapter,
we discuss the present and future applicability of 3D power Doppler ultrasound in
obstetrics. 3D power Doppler ultrasound may become an important modality in future
research on fetal and placental blood flow, and assist in prenatal diagnosis of the fetal
and placental vascular abnormalities.
