Vascular and Ultrasound - Peripheral Vascular – Peripheral Artery Disease – Vascular – Doppler – Explained Here: What Does 'Vascular' Mean? The word vascular refers to our body's circulatory system — the blood vessels which carry blood from the heart to the body's organs (the arteries) and from the organs back to the heart (the veins). What is a vascular ultrasound scan? A vascular ultrasound is a noninvasive ultrasound method (also called a duplex study) used to examine the circulation in the blood vessels of the body. Vascular ultrasound can be used to evaluate arteries or veins in nearly any part of the body, including blood vessels in the neck, abdomen, arms and legs. What does a vascular test consist of? A vascular study is an ultrasound of an area of the body designed to specifically capture images of the main arteries in that area. They are performed to help physicians identify blockages to blood flow (clots), narrowing of the vessels (stenosis), and enlargement of arteries (aneurysm). What is a Doppler Ultrasound? A Doppler ultrasound is a noninvasive test that can be used to estimate your blood flow through blood vessels by bouncing high-frequency sound waves (ultrasound) off circulating red blood cells. A regular ultrasound uses sound waves to produce images, but can't show blood flow. What is an arterial Doppler test? This test uses ultrasound to examine the blood flow in the major arteries and veins in the arms and legs. The test is done in the ultrasound or radiology department or in a peripheral vascular lab.
