Carotid Artery Stenosis: Should You Get Tested?
Published: May 22, 2024
Carotid artery stenosis tests are available, but they come with their own set of challenges. Are these tests right for you?
Types of Tests
There are several noninvasive tests available for carotid artery stenosis, including carotid duplex ultrasonography, magnetic resonance angiography, and computed tomography angiography. These tests are used to identify narrowing in the carotid arteries, offering high sensitivity and specificity.
Limitations of Testing
Despite their accuracy, these tests can lead to false positives, causing unnecessary anxiety and interventions. The reliability of the tests can vary between different laboratories and operators.
When Testing is Advised
Testing is generally not recommended for asymptomatic individuals. However, it may be considered for those with significant risk factors or symptoms of atherosclerosis in other parts of the body.
Frequently Asked Questions
Ultrasonography, MRI, and CT scans.
Yes, but they can cause false positives.
Those with risk factors or symptoms elsewhere.
The Bottom Line
Testing for carotid artery stenosis should be carefully considered based on individual risk factors.
