Carotid Doppler Ultrasound

A carotid Doppler ultrasound is a non-invasive, painless test that uses sound waves to evaluate blood flow through the carotid arteries — the major vessels in the neck that supply blood to the brain. This test helps detect narrowing or blockages that could increase the risk of stroke or other vascular problems.

A carotid Doppler may be ordered if there are risk factors such as high blood pressure, high cholesterol, diabetes, or a history of smoking, or if an abnormal sound (bruit) in the neck is detected. It can help reveal early signs of Carotid artery stenosis and guide treatment to prevent serious complications like stroke.
