HOW DOES A CAROTID ULTRASOUND WORK?
A technician (sonographer) conducts the test with a small, hand-held device called a transducer. The transducer emits sound waves and records the waves as they bounce off tissues, organs and blood cells.
The computer translates the sound waves into a live-action image on a monitor.
You will lie on your back during the ultrasound. The ultrasound technician (sonographer) may position your head to better access the side of your neck.
The sonographer will apply gel to your skin above the site of each carotid artery. The gel helps transmit the ultrasound waves. The sonographer then gently presses the transducer against the side of your neck.
You shouldn’t feel any discomfort during the procedure. The procedure will take approximately 20-45 minutes to complete.
