Atherosclerosis is a progressive and degenerative disease of the artery wall which begins relatively early in life, years if not decades prior to the onset of clinical signs and symptoms. One of the major challenges which face investigators in this field of research is to establish the validity and reliability of noninvasive methods which can detect atherosclerotic plaques before they become severe enough to result in tissue ischemia, and to determine whether or not atherosclerotic lesions can be monitored both in terms of rate and direction over time. Although several methods of direct arterial visualization are available currently, high-resolution B-mode ultrasound imaging appears to have the most advantages. This technique is noninvasive, relatively inexpensive, and can visualize not only lumen contour and configuration, but also the atherosclerotic plaque in the underlying wall. Preliminary experiments in animal models suggest that lesions as small as 0.5 mm in the carotid arteries can be detected using this method. Whether or not atherosclerotic plaques can be monitored over time, however, has not been demonstrated. |
