1. Middle cerebral artery Dopplers to screen for fetal anemia
Middle cerebral artery Dopplers to screen for fetal anemia. Color Doppler is used to identify the circle of Willis. The Doppler calipers are placed on the proximal third of the middle cerebral artery at a 0-degree angle (ie, dotted line overlaps the length of the middle cerebral artery). The peak systolic velocity is measured by measuring the peak of the waveforms.
