A carotid artery ultrasound is a test used to detect blockages in the carotid arteries, which are the two main arteries that supply blood to the brain. What is a carotid ultrasound?
It is a non-invasive imaging test that uses sound waves to create pictures of the carotid arteries. When would a carotid ultrasound be needed?
It is typically used to detect narrowing of the carotid arteries, which can be caused by plaque buildup, and can increase the risk of stroke. Who performs a carotid ultrasound?
A trained technician or doctor will perform the test.
How does a carotid artery ultrasound work?
The technician will use a transducer, which is a device that sends and receives sound waves, to create images of the carotid arteries. The technician will move the transducer over the neck area to create the images. How do I prepare for the test?
You should wear loose-fitting clothing and avoid wearing jewelry or other metal objects. You may also be asked to remove any clothing or jewelry that may interfere with the test.
What to expect on the date of the test?
You will be asked to lie down on an exam table and the technician will apply a gel to the neck area. The technician will then move the transducer over the neck area to create the images. What to expect during a carotid ultrasound?
You may feel slight pressure from the transducer, but the test is painless. What to expect after a carotid artery ultrasound?
After the test, you can resume your normal activities.
What are the risks of a carotid ultrasound?
There are no known risks associated with the test. What type of results do you get and what do the results mean?
The results will show if there is any narrowing of the carotid arteries. If narrowing is detected, your doctor may recommend further testing or treatment. Stroke risk factors
include high blood pressure, smoking, diabetes, and high cholesterol.
When should I know the results of the test?
The results of the test will usually be available within a few days. When should I call my doctor?
You should call your doctor if you have any questions or concerns about the results of the test.
