Outline of Final Research Achievements

The main objective of this study was to assess cardiac death (CD) kidney grafts before transplantation to determine whether blood oxygen level-dependent (BOLD) and diffusion MRI techniques can predict damage to these grafts after transplantation. We succeeded in evaluating cardiac death donor kidney graft tissue injury by detecting red blood cell accumulation and intra-cellular or outer-cellular edema with BOLD and diffusion MRI respectively. We assessed CD kidney tissue by BOLD and diffusion MRI. We showed that BOLD and diffusion MRI, which are readily available non-invasive tools for evaluating CD kidney grafts tissue damage, can predict prolonged organ damage, and therefore the outcome, of transplanted CD kidney grafts.（Kaimori J et.al, PlosOne 2013）
