This test uses ultrasound to evaluate blood flow in the neck arteries (carotid arteries), and/or in the veins and arteries of the arms and legs. Vascular testing may also be used to evaluate the abdominal aorta. It can detect narrowing of arteries, which may reduce the blood flow through these vessels, or atherosclerosis (“hardening of the arteries”). Vascular testing is performed in our office by Registered Vascular Technologists using state-of-the-art high frequency ultrasound equipment. Depending on the type of study requested the test might take from 45 to 90 minutes. You will receive preparation instructions for this test when it is scheduled.
