What is a Carotid Duplex?
The carotid duplex test uses imaging and ultrasound waves to look at and listen to the major blood vessels in the neck, the carotid arteries and their branches, leading to the brain. A visual image is taken of the arteries with no discomfort to the patient whatsoever. A clear gel is applied to the neck during the examination, so no turtlenecks or high neck shirts, scarves, etc. should be worn. The test is painless and the patient should allow 45-60 minutes for the study.
