Carotid Ultrasound Scan
Carotid ultrasound scan is a non-invasive imaging test used to assess the carotid arteries, which supply blood to the brain, neck and face. This scan helps detect narrowing, blockages or plaque buildup that could increase the risk of stroke.
What is a carotid ultrasound scan?
Used to assess the health of the carotid arteries, a carotid ultrasound scan is a non-invasive imaging test that helps detect narrowing or blockages that may indicate an increased risk of stroke or other vascular conditions. This safe and painless procedure provides real-time images of blood flow and arterial structure, aiding in early diagnosis and preventive care.
Why would you need a carotid ultrasound?
A carotid ultrasound is recommended for individuals at risk of stroke or cardiovascular disease, particularly those with high blood pressure, diabetes or a history of smoking. The scan is also used for monitoring existing vascular conditions or evaluating symptoms such as dizziness, vision changes, or unexplained weakness.
How should I prepare for a carotid ultrasound?
Preparing for a carotid ultrasound is simple and requires minimal effort. Patients may be advised to avoid wearing high-neck clothing or jewellery around the neck area to allow easy access for the scan. In most cases, no fasting or special preparation is needed, but your healthcare provider will inform you of any specific prior instruction.
What happens during a carotid ultrasound procedure?
During a carotid ultrasound, a specialist applies a small amount of gel to the neck to help the ultrasound probe glide smoothly over the skin. The probe emits sound waves that create real-time images of the carotid arteries, allowing the specialist to assess blood flow. You will be asked to lie still while the probe moves along both sides of your neck to capture detailed visuals from different angles.
What can a carotid ultrasound detect?
A carotid ultrasound can detect blockages, narrowing (stenosis, or plaque buildup in the carotid arteries, which may increase the risk of stroke. It can also identify abnormal blood flow, blood clots or structural abnormalities in the arteries. By assessing these factors, the scan helps in diagnosing conditions such as atherosclerosis and evaluating overall vascular health.
How long does a carotid ultrasound take?
A carotid ultrasound is a quick and non-invasive procedure, typically lasting between 15 to 30 minutes. The exact duration may vary depending on the complexity of the assessment and the clarity of the images required. Once completed, the specialist will review your results and determine if further evaluation is necessary.
Is a carotid ultrasound a reliable test?
A carotid ultrasound is a highly reliable and widely used test for assessing blood flow and detecting abnormalities in the carotid arteries. It provides real-time imaging that helps identify blockages, plaque buildup and narrowing of the arteries with great accuracy. While it is an effective screening tool, additional tests may be required in certain cases.
