X-ray computed tomography of the cardiovascular system

X-ray CT of the heart is an evolving field. The ultrafast CT scanner provides a practical method of applying the high spatial resolution, high density resolution, and tomographic capabilities of conventional CT scanning, permitting an evaluation of the cardiovascular system. Multiple reports demonstrate that the basic ultrafast technology, while in an evolving state, permits comprehensive evaluation of cardiac structure and function. Recent studies suggest that with further modification ultrafast CT may ultimately be able to delineate the anatomy of the proximal coronary arteries and bypass grafts and to quantitate perfusion. If all these are possible, x-ray CT will have an expanded role in the evaluation of patients with known or suspected heart disease.
