[Contribution of the electron beam scanner (Imatron) in aortic pathology].

Electron Beam CT (SFE, Imatron) uses electron beam to generate X rays. This allows the shortest acquisition time today available (50-100 ms). It is the best CT examination for moving structures. In vascular disease arterial wall study is the most important end point, especially in aortic pathology. EBCT is effective in aortic aneurysm, dissection and aortitis diagnosis. It allows a pre-surgical mapping of the lesion and follow-up. We believe that EBCT is superior to other diagnostic mean in the assessment of the ascending aorta and of small arterial lesions.
