This test can help doctors to determine stroke risk and help determine preventive measures.
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 narrow due to arteriosclerosis or other causes and this can lead to TIA (mini-stroke) or CVA (stroke).
What to Expect
How is this procedure done?
You will lay face-up on an exam table, then the technician will apply a warm water-based gel to the area that will be examined. The gel helps the transducer make secure contact with the skin.
Then the tech will move the transducer back and forth until the desired images are captured.
Is this test painful?
Usually no, unless the transducer is applied to a tender area.
