Duplex Ultrasonography

Basic Facts

Ultrasound is a painless, non-invasive, radiation-free diagnostic test that uses high-frequency sound waves to create images of body tissues.

Duplex ultrasound also allows physicians to measure the velocity of blood flow and to see the structure of the blood vessels through which the blood is flowing.

Physicians use duplex ultrasound to diagnose and examine diseases that affect the blood vessels, as well as to plan for and evaluate surgical and interventional therapies.

About Ultrasound

Ultrasound is a tool that a physician uses to gather information about a patient beyond his or her medical history and a physical examination. For example, ultrasound allows a physician to evaluate the veins and arteries in a person’s body and to watch blood as it flows through blood vessels. Duplex ultrasonography is a form of ultrasound that produces images that differentiate between the body’s soft tissues and its fluid-filled structures. Duplex ultrasound can also detect motion, such as the movement of blood cells.

Duplex Ultrasonography
Duplex ultrasound is used to detect the presence and severity of numerous conditions, including:

  • Thrombosis (blood clots)
  • Blockages from atherosclerosis (hardening of the arteries)
  • Thrombophlebitis (an inflammation of the blood vessels)
  • Trauma to an artery or vein
  • Raynaud’s phenomenon (a spasm of small blood vessels in the fingers) and
  • Increases in the thickness of the blood vessel lining.
