Arterial blood flow

Preservation of adequate blood flow and exclusion of flow from lesions are key concepts of vascular neurosurgery.

see Cerebral blood flow

Vascular studies use high-frequency sound waves (ultrasound) to measure the amount of blood flow in your blood vessels. A small handheld probe (transducer) is pressed against your skin. The sound waves move through your skin and other body tissues to the blood vessels. The sound waves echo off of the blood cells.
