Feasibility study demonstrates a 50% reduction in contrast media for coronary CT angiography in a dynamic vessel phantom, indicating potential for safer imaging protocols.
Using virtual monoenergetic image reconstructions at 40 keV on a dual-source PCD-CT system, contrast media concentration could be reduced by 50% to obtain diagnostic attenuation and objective image quality for coronary CT angiography in a dynamic vessel phantom. These initial feasibility study results have to be validated in clinical studies.
