It essentially measures the thickness of the wall of the carotid artery in the neck. This is a good non invasive way to detect vascular disease in its earliest stages. By detecting the early stages of vascular disease, doctors can take preventive measures to help slow its progression. Dr. James Stein. Univ. of Wisconsin.
