Carotid Doppler Ultrasound

A carotid Doppler ultrasound, also called a carotid ultrasound, is a painless, non-invasive imaging test that uses sound waves to evaluate blood flow through the carotid arteries on each side of your neck. These arteries provide blood to your brain.

Carotid ultrasound can help detect narrowing or blockage of the carotid arteries caused by plaque buildup in appropriately selected patients. Significant narrowing of these arteries can increase the risk of stroke.

Your physician may recommend carotid Doppler ultrasound based on symptoms, physical examination findings, known vascular disease, or other clinical considerations.

Because carotid ultrasound uses sound waves rather than radiation, the examination is non-invasive and generally well tolerated. Results can help your physician determine whether additional evaluation, medical treatment, lifestyle changes, or specialist referral may be appropriate.
