Ultrasonic imaging of aortic atheroma
| The first 150 words of the full text of this article appear below. |
The study of embolism in the cerebral and peripheral circulation requires imaging methods that reveal pathology in some part of the heart or circulation upstream of the occluded vessel. Technological advances over the past 10-15 years, and in particular the development of transoesophageal, epiaortic, and intravascular ultrasound has made it possible to obtain high resolution images of atherosclerotic lesions in arteries, allowing study of coronary, cerebral, and peripheral vessels as well as the aorta. For aortic disease, transoesophageal and epiaortic ultrasonography have the advantage over other imaging methods, such as computerised tomography or magnetic resonance imaging, of providing real-time images that allow for the evaluation of plaque morphology, ulceration, and mobility. The disadvantages are that transoesophageal ultrasound is semi-invasive and has a blind spot (the upper part of the ascending aorta) and epiaortic ultrasound can only be used intraoperatively.
