The ultrasound waves will produce a picture of your arteries on the ultrasound machine that will allow the technologist to assess your arteries for blockage and check the blood flow through the arteries. The technologist will take several pictures from several different areas of your leg. During the exam and you may hear noises that sound like your heart beat as your blood flow is being assessed. You will feel nothing during the exam except for slight pressure as the probe is placed against your skin. The exam will take 30-45 minutes for one leg and up to 90 minutes for both.
