Carotid doppler ultrasound is a non-invasive test that uses sound waves to measure the flow of blood through the large carotid arteries that supply blood to the brain. These arteries can become narrowed due to arteriosclerosis or other causes, and this can lead to transient ischemic attack (mini-stroke) or cerebral vascular accident (stroke). The carotid doppler test can help doctors determine stroke risk and the need for preventive measures.
Why Do I Need To Have a Carotid Doppler Test?:
A carotid doppler test may be performed if you have had a stroke, or, if based on your doctor’s evaluation, you are considered to be at increased risk of having a stroke due to decreased blood flow in the carotid arteries.
