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.
Reasons
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).
Risks
This is a no-risk test.
