Doppler Ultrasound Evaluation of the Fetus and Placenta

Abstract Doppler ultrasound can be used to assess vascular beds in the maternal, fetal, and placental circulation. The vessels most frequently evaluated in clinical practice are the uterine, umbilical and (fetal) middle cerebral arteries, and the ductus venosus. Evaluation of blood flow in various vascular beds, combined with clinical information, provides insight into maternal adaptation to pregnancy, placental resistance, and fetal cardiovascular status, and may therefore guide pregnancy management.
