What is Middle Cerebral Artery Peak Systolic Velocity (MCA PSV)?
Middle cerebral artery peak systolic velocity (MCA PSV) is a Doppler ultrasound measurement used to assess blood flow velocity in the middle cerebral artery of the fetus. This measurement is crucial in identifying fetal anemia, particularly in cases of Rh isoimmunization, where the fetus may be at risk for hemolytic disease.
