![]() The radiologist also may discuss the results of the test with you immediately after the procedure. ![]() This may be your health care provider, a doctor trained in heart and blood vessel conditions, called a cardiologist, or a doctor trained in brain and nervous system conditions, called a neurologist. ResultsĪ doctor who specializes in imaging tests, called a radiologist, will review your test results, then prepare a report for the health care provider who ordered the test. If you do, tell the ultrasound technician. You shouldn't feel any discomfort during the procedure. The technician then gently presses the transducer against the side of your neck. The gel helps transmit the ultrasound waves back and forth. The ultrasound technician will apply a warm gel to your skin above the site of each carotid artery. The ultrasound technician may position your head to better access the side of your neck. You'll likely lie on your back during the ultrasound. There have been vast technological advances in carotid ultrasounds, improving the quality and resolution of the images.Ī carotid ultrasound usually takes about 30 minutes. In a Doppler ultrasound, the rate of blood flow is translated into a graph. The ultrasound technician may use a Doppler ultrasound, which shows blood flowing through the arteries. The transducer emits sound waves and records the echo as the waves bounce off tissues, organs and blood cells.Ī computer translates the echoed sound waves into a live-action image on a monitor.
