Carotid ultrasound
Informed by recognized medical guidance
Overview
A carotid ultrasound is a painless test that uses sound waves to create pictures of the carotid arteries – the large blood vessels on each side of your neck that carry blood to your brain. It checks for narrowing or blockages that can increase your risk of stroke.
Key facts
- Carotid ultrasound is also called carotid duplex ultrasound.
- It is a non-invasive test – no needles or radiation involved.
- The test takes about 30 to 45 minutes and is done in a hospital or clinic radiology department.
- It is often used to find plaque buildup (fatty deposits) in the carotid arteries.
Carotid ultrasound is a common and routine test, especially for people over 50 or those with risk factors like high blood pressure or diabetes.
