The fetal middle cerebral arterial (MCA) peak systolic velocity (PSV) is an important parameter in fetal MCA Doppler assessment.

Measurement

The fetal MCA should be sampled~2 mm from the origin of the fetal internal carotid artery and the angle of the ultrasound beam and the direction of blood flow should be 0°. Usually, the highest peak systolic velocity (PSV) value is taken.
