A carotid duplex scan is a simple and painless test that combines two types of ultrasound to look for blockages in your carotid arteries. An ultrasound is a type of scan that uses sound waves to produce a picture of the inside of your body. Your carotid arteries are located along both sides of your neck. Blocked carotid arteries are a major risk factor for stroke.

Venous duplex scan is a painless exam that uses high-frequency sound waves (ultrasound) to capture internal images of the veins in the arms, legs and neck.

Arterial duplex scan is a painless exam that uses high-frequency sound waves (ultrasound) to capture internal images of the major arteries in the arms, legs and neck.

The aorta is the largest artery in the body. It carries oxygenated blood from the heart through the chest and torso to the rest of the body. An aneurysm is an abnormal enlargement of part of a blood vessel. Thus, an abdominal aortic aneurysm is a balloon-like bulge in the portion of the aorta that runs through the abdomen.

Pulse volume recording (PVR) is a non-invasive imaging test that evaluates the lower or upper extremity arterial flow.
