Atherosclerotic disease in the thoracic aorta has been linked to an increased risk of thromboembolic events (such as embolic stroke or ischemic bowel) and an increased risk of mortality and stroke, especially for asymptomatic at-risk patients. It is very important to reliably identify aortic plaques. But the thoracic aorta located deep in the chest, it is difficult to directly evaluate the vessel wall condition with high resolution images. In this study, new MR was optimized and evaluated for the screening of the thoracic aorta atherosclerotic plaques.
