320-slice Coronary Computed Tomography (CT) Angiography

Coronary Artery Imaging With 320-slice Computed Tomography

The primary aim of this study is to determine the potential utility of 320-slice volume-CT for obtaining adequate diagnostic accuracy while at the same time improving image quality compared with previous generations of CT scanners and simultaneously enabling a reduction in both radiation exposure and contrast agent amount required.
