What it is
A carotid ultrasound uses sound waves and Doppler to look at the arteries in the neck that carry blood to the brain. It checks for narrowing or plaque and is ordered after a stroke or mini-stroke, for a bruit heard in the neck, or to follow known artery disease.
What the price covers
The hospital price usually covers the complete study of both sides. The interpretation by a radiologist or vascular specialist is often billed separately.
