Carotid duplex scan is an ultrasound test that shows how well blood is flowing through the carotid arteries. The arteries are located in the neck, and they supply blood directly to the brain.
No preparation is necessary and there are no known risks with this procedure.
This test checks blood flow in the carotid arteries. It can detect blood clotting (thrombosis), narrowing in the arteries (stenosis), and other causes of blockage in the carotid arteries.
Test results are sent to your doctor for evaluation. Your doctor will share these results with you.
