Diagnosing Carotid Artery Disease: Which Tests Might You Need?

The Big Picture

Accurate diagnosis of carotid artery disease is crucial for preventing strokes. Several tests can help doctors assess the health of your carotid arteries.

Carotid Duplex Ultrasound

This non-invasive test uses sound waves to create images of your carotid arteries. It's usually the first test performed and can show how much your arteries are narrowed. The test is painless and takes about 30 minutes.

CT Angiography (CTA)

CTA uses X-rays and computer processing to create detailed images of your carotid arteries. A contrast dye is injected into your arm to make the arteries more visible. This test can provide more detailed information than ultrasound.
A comprehensive evaluation using carotid duplex ultrasound and CT angiography to assess the health of carotid arteries and prevent strokes.

Magnetic Resonance Angiography (MRA)

MRA uses powerful magnets and radio waves to create detailed images of your carotid arteries. It doesn't use radiation and can show both the structure of your arteries and blood flow. Some people may need an injection of contrast dye.

Cerebral Angiography

This invasive test involves inserting a catheter into an artery and injecting contrast dye. It provides the most detailed images but carries more risks than other tests. It's usually only done if other tests are inconclusive or more information is needed.

FAQs

Are these tests painful?

Most are painless; angiography may cause brief discomfort.

How long do the tests take?

From 30 minutes for ultrasound to several hours for angiography.

Will I need multiple tests?

Possibly, depending on your specific situation.

Are there risks from the contrast dye?

Rarely; tell your doctor about any allergies.

How often should I be tested?

Your doctor will advise based on your risk factors.
