Multiple contrast agent imaging using MARS-CT, a spectroscopic (multi-energy) photon counting microCT scanner
Purpose: To establish that a spectroscopic (multi-energy) CT scanner can differentiate multiple contrast agents and background tissues. This is clinically significant because it enables multi-phase contrast studies to be performed in a single scan. eg. A "triple phase liver" is possible in a one acquisition. This is a significant improvement from dual energy CT which is limited to non-contrast and post-contrast images from a single acquisition.
