A Carotid sonogram provides images of the carotid arteries, located on both sides of the neck. The test measures the velocity of the blood flow through these arteries to screen for plaque buildup. This test is designed to assess the risk for stroke and TIA, most commonly caused by carotid artery stenosis. Early detection & treatment can help decrease the possibility of stroke. Carotid sonography is also a useful tool to evaluate other cardiovascular diseases. How the test is performed: The technologist applies a water soluble acoustic gel on your neck over your carotid arteries.
