The purpose was to explore whether quantitative susceptibility mapping (QSM) can assess the dynamic process of renal ischemia-reperfusion injury (IRI) in rabbits. We found that the magnetic susceptibility values of the outer medulla were statistically significant among the IRI group. Additionally, the magnetic susceptibility values of the outer medulla was highly correlated with the pathological score of renal injury. With these findings, QSM could serve as a quantitative biomarker to assess the dynamic changes of the outer medulla in the early stage of renal IRI.
