Carotid arteries are large blood vessels that carry oxygen-rich blood from the heart to the brain. If these important arteries become clogged with plaque, blood flow is restricted and can become turbulent. Pieces or clots of blood can break off and travel to the brain causing a stroke.
A Carotid Doppler Ultrasound Test is a quick and painless test that uses high frequency sound waves to create a real-time image of the carotid arteries and the blood flowing through them. This test can detect narrowing of the arteries due to plaque build up and disclose any splits within the layers of the artery walls. If plaque or narrowing of the vessel is found, treatment can be prescribed to help prevent dangerous clots from moving to the brain. Carotid Doppler Ultrasound is an important screening tool for anyone with risk factors for stroke.
