Carotid Artery Disease
The aorta is the largest blood vessel in your body. The aorta carries all the blood that is pumped out of your heart and branches progressively to distribute blood to all of the organs and throughout the body. The carotid arteries branch off the aorta and deliver blood to your head and brain. Coronary arteries branch from the aorta, which supply the heart with oxygen, blood, and nutrients to keep it healthy.
A carotid duplex ultrasound can detect most cases of carotid artery disease. To conduct the test, your doctor will simply move a small device over your carotid arteries. The device transmits sound waves that compose an image of your carotid arteries. If the carotid duplex ultrasound does not provide enough information, additional tests may be performed.
Magnetic resonance angiography (MRA) produces extremely detailed views of the blood vessels. Computed tomography (CT) and computed tomography angiography (CTA) produce images in sections that make up a whole picture of your brain or arteries. These tests are used to identify areas of poor blood flow and arterial narrowing. A dye and X-ray are used to show an image of the blood vessels with an angiography.
