Vascular Duplex Ultrasound

A duplex ultrasound combines traditional ultrasound with doppler ultrasound.

  • Traditional ultrasound uses sound waves that bounce off blood vessels to create pictures.
  • Doppler ultrasound records sound waves reflecting off moving objects, such as blood, to measure their speed and other aspects of how they flow.
  • A vascular ultrasound allows visualization of major blood vessels. The vessels can be evaluated for blockage, narrowing or enlargement. Ultrasound can assess the blood vessels in the legs, arms, body, and neck.

There are different types of duplex ultrasound exams. Some include:

  • Arterial and venous duplex ultrasound of the abdomen examines blood vessels and blood flow in the abdominal area.
  • Carotid duplex ultrasound looks at the carotid artery in the neck.
  • Duplex ultrasound of the extremities looks at the arms or legs.
  • Renal duplex ultrasound examines the kidneys and their blood vessels.

A duplex ultrasound can help diagnose the following conditions:

  • Abdominal aneurysm
  • Arterial occlusion
  • Blood clot
  • Carotid occlusive disease
  • Renal vascular disease
  • Varicose veins
  • Venous insufficiency
