Carotid Ultrasound: What It Is & Why It's Used

A carotid ultrasound is a non-invasive medical test used to assess the condition of the carotid arteries in the neck. These arteries are responsible for supplying blood to the brain, and carotid ultrasounds can identify any abnormalities or conditions that may affect blood flow to the brain, such as:

- Narrowing or blockage of the carotid arteries (carotid stenosis)

- Plaque buildup in the arteries (atherosclerosis)

- Blood clots or emboli in the arteries

- Abnormal structures or conditions, such as aneurysms or dissections

- Carotid ultrasounds use sound waves to create detailed images of the carotid arteries and measure the blood flow within them, helping doctors diagnose various conditions related to the carotid arteries and assess the risk of stroke.
