Vascular Ultrasonography

Vascular ultrasound is a noninvasive ultrasound method (also called a duplex study) used to examine the blood circulation in the arms and legs to evaluate:

• blood flow in the arteries in your neck that supply blood to the brain
• blood flow to a newly transplanted organ
• blood flow in the arteries to detect the presence, severity and specific location of a narrowed area of the arteries
