Abstract
In routine obstetric scanning of the fetal cranium, the near or proximal portion of the fetal cerebrum is obscured by reverberation caused by overlying cranium. A new technique is described in which the ultrasound probe is angled in relation to the bony calvarium to allow visualization of the more proximal fetal cerebrum, cerebral ventricle, and choroid plexus.
