USG Doppler in Obstetrics is the evaluation of vascularity and blood flow within the uterus (both gravid and nongravid), ovaries, fetus and placenta. In the future, color Doppler may also be used in the three-dimensional reconstruction and visualization of fetal and placental vessels.
Doppler in Obstetrics diagnoses the fetal cardiac defects and also assess the hemodynamic responses to fetal hypoxia and anemia.
