Abstract
The millisecond image acquisition time characteristic of the ultrafast
computed tomography (UFCT) scanner makes it an ideal modality for
evaluating patients with suspected vascular lesions of the thoracic aorta.
Unlike conventional CT, the UFCT electron beam technology produces images
with excellent resolution, minimal respiratory artifact, and superior
vascular enhancement. This report discusses the (1) basic characteristics
of the UFCT scanner as they relate to the imaging of the thoracic aorta,
(2) UFCT appearances of uncomplicated and complicated aneurysms and
dissections, (3) appropriate CT protocols used in the work-up of suspected
thoracic aortic disease, and (4) strengths and weaknesses of other imaging
modalities compared with UFCT. [References: 14]
