A normal result means there is no problem with the blood flow in the carotid arteries. The artery is free of any blockage, narrowing, or other problem.
Note: Talk to your doctor about the meaning of your specific test results.
What do Abnormal Results Mean?
An abnormal result means there are disturbances in the blood flow in the carotid arteries. This is a sign of atherosclerosis or blood vessel conditions.
Depending on the exact results, your doctor may want you to:
- Follow a healthy diet and lifestyle to prevent atherosclerosis
- Repeat the test again in the future
- Have additional tests (such as cerebral angiography, CT angiography, and MR angiography)
- Consider surgery
See the article on atherosclerosis for further treatment information.
