A carotid Doppler ultrasound is a painless procedure that measures the amount of blood flow in the carotid arteries. The carotid arteries are the two major arteries on each side of the neck that carry blood to the head.

The Doppler takes about 30-45 minutes. The technician will place a clear gel on the side of your neck. She will then use a sensor that looks like a wand to get an ultrasound image of rate of blood flow through your carotid arteries. Any narrowing of the arteries will show up as an area of reduced blood flow.

Why is a carotid Doppler done?
Carotid Doppler scanning is used to evaluate the risk of stroke in patients who have a history of stroke or are at high risk.

What preparations are needed?
No special preparations are needed for this procedure.
