Fetal Doppler: Umbilical Artery, Middle Cerebral Artery, and Venous System. cerebroplacental ratio (CPR): ratio of pulsatility index of MCA and umbilical artery.fetal MCA systolic/diastolic (S/D) ratio: a normal fetal MCA S/D ratio should always be higher than the umbilical arterial S/D ratio.fetal MCA peak systolic velocity (PSV): the highest velocity should be recorded.The reading should be obtained close to its origin in the internal carotid artery as the systolic velocity decreases with distance from the point of origin of this vessel. An angle of insonation of <15° should be used typically, an angle that approximates 0° can be achieved by moving the transducer on the maternal abdomen. An axial section of the brain, including the thalami and the sphenoid bone wings, should be obtained and magnified. The MCA vessels are often found with color or power Doppler ultrasound overlying the anterior wing of the sphenoid bone near the base of the skull. For an accurate measurement, the fetal head should be in the transverse plane.
