Quick Facts

What is a Carotid Doppler ?

This painless, noninvasive test is used to see and measure the rate at which blood flows through your carotid arteries and look for possible blockages. No radiation, dye or needles are used. The test may be performed in a vascular laboratory, a doctor’s office or a radiology department.

What are the risks of this procedure ?

This is a "no-risk" test.

Why is this test done ?

You may be given a carotid duplex test to determine whether plaque has accumulated in your arteries, causing carotid artery disease (hardening of the arteries).

  • Description
  • How to Prepare
  • What to Expect
  • Wearing your street clothes, you will be asked to lie on a stretcher.  
  • Ultrasound gel, usually warmed for your comfort, will be placed on either side of your neck.  
  • Through the gel, the technician will apply to your neck a small hand-held device that emits sound waves. 
  • When the test is completed, the technician will remove excess gel from your neck. The gel is water-soluble and will not stain your skin or clothes.
  • Eat and take medications as usual.
  • Wear minimal or no jewelry to ease application and removal of gel.

The technician will send the ultrasound images to your vascular surgeon for evaluation. Typically, a report is available in 2–3 days. If anything critical is found, it is standard practice at most labs to notify the vascular surgeon immediately.
