In this study, liver disease in rats was evaluated using a photon-counting CT (PC-CT) system developed with a YGAG:Ce scintillator and an MPPC. Following the administration of an MRI contrast agent (Gd-EOB) to healthy and fatty liver model groups, we observed accumulation specific to the healthy group, demonstrating the efficacy of PC-CT in liver function assessment. Furthermore, the estimated liver fat fraction showed good agreement with results from dual-energy CT and MRI. This presentation reports the potential of PC-CT for quantitative evaluation of liver diseases from a multimodality perspective.
