Ultra-High Resolution (0.2mm, 1024 matrix) coronary CTA scan demonstrates improved visualization of small coronary branches and distal vessels

Small branch vessels are better visualized with Ultra-High Resolution (0.2mm, 1024 matrix) scans

Fine anatomic details of cardiac valves, chordae tendinea, and papillary muscles are able to be seen

Clear visualization of stent struts and reduced partial volume effect minimizes blurring and improves stent edge sharpness
