Middle cerebral artery (MCA) doppler, is a type of ultrasound used to detect the blood flow to the fetus's brain. It is a non-invasive procedure that measures the peak systolic velocity of the blood flow to the baby's brain. In anemia, the blood travels too fast. In polycythemia, the blood appears to travel too slowly. Thus, these can be used to diagnose TAPS (twin anemia polycythemia sequence).
