What is a carotid ultrasound?
Ultrasound is a noninvasive test using high-frequency sound waves with a water-soluble gel and a small probe to produce an anatomical image of soft tissue structures in the neck. A carotid ultrasound can evaluate for interruption of blood flow and blockage(s) in the arteries caused by significant plaque. Carotid artery ultrasound uses no radiation, dyes or needles.
Identifying early disease, monitoring disease progression and assessing surgical interventions are some of the advantages of using ultrasound.
Why should I have this test performed?
If your physician suspects you have carotid artery disease, you will be scheduled for a carotid ultrasound test. Your doctor may recommended this test based on your physical examination, past medical history or signs and symptoms you are currently experiencing.
How long will the test take?
A carotid ultrasound takes approximately 45 minutes to complete.
How do I prepare for a carotid ultrasound?
No special preparation is needed. You may eat a full meal and take your regular medications as prescribed.
How is the test performed?
- Blood pressures will be taken in both arms, unless otherwise indicated.
- You will then be asked to lie on your back with your head tilted to one side.
- The sonographer will apply a water-soluble gel to the neck area being evaluated.
- The sonographer will slide an ultrasound probe over the arteries in your neck. It is important to remain still so optimal images can be taken.
- You will hear noises while the sonographer listens for blood flow and records measurements.
- The same technique is then performed on the other side of your neck.
