Carotid Ultrasound is a painless and harmless test that uses a high frequency sound wave to create pictures of the insides of the two large arteries in your neck. These arteries, called the carotid arteries, supply your brain with oxygen rich blood. You have one carotid artery on each side of your neck.
There is no special preparation for a carotid ultrasound.
The carotid examination procedure can take up to 20 minutes.
