Carotid Artery Sonogram

The purpose of a Carotid Artery Sonogram is to assess the stroke risk from carotid artery stenosis or narrowing of the carotid arteries. These are the main arteries in the neck that supply blood to the brain.

Following are some frequently asked questions about the test and how to prepare for it. Click on the question for the answer, which will appear below the questions.

What will happen during this test?

This test takes approximately thirty minutes. This is accomplished by placing a transducer on your neck with a small amount of ultrasound gel. The transducer sends sound waves through your neck to the carotid arteries and back. Then with the aid of computer software and a monitor we are able to image your arteries and display it on a monitor in front of you.

In conjunction with this imaging we will assess the blood flow with both pulsed Doppler and Color Flow Doppler, which measure the speed and direction of the blood flow. By assigning color to the direction of blood flow—called Color Flow Mapping—large areas of blood flow may be studied, which allows abnormal blood flow characteristics to be interpreted by the cardiologist.

After you leave the laboratory the technologist will document measurements from the images. A Legacy Heart Center physician will review the images and measurements. If you have had a previous study the results will be compared.

What is the preparation for the test?

If you routinely take any medications take them as prescribed.
