64-slice CT scanners are said to have significantly improved CT Angiography (CTA), and is particularly recommended for cardiac studies. The speed and sensitivity of these scanners allow physicians to see how well the heart is contracting, to view the walls of arteries for plaque formation, and to observe the tiniest of vessels and arterial branches. They can produce exceptionally sharp images of the finest details and significantly reduce scan time. Here is a comparison of the GE LightSpeed VCT Select and the Philips Brilliance 64.
