Electron beam computed tomographic imaging of aortic aneurysms and dissections

Electron Beam Computed Tomography (EBCT), like conventional CT has the capability to acquire high resolution images of the aorta. The millisecond image acquisition time characteristic of EBCT makes it an ideal modality to evaluate patients with suspected aneurysms or dissections of the aorta. Unlike conventional CT, electron beam technology produces images with excellent resolution, minimal respiratory artifact, and superior vascular enhancement. Compared with alternative modalities, EBCT probably represents a superior tool in the workup of aortic pathology. Whether in the acute or chronic setting, the reliability, speed, ease, and reproducibility of EBCT makes it truly superior in the diagnosis and follow-up of aortic aneurysms and dissections.
