Keywords: Small Animals, Quantitative Imaging, kidney，remote ischemia preconditioning，Oxidative Stress
Motivation: Remote ischemic preconditioning can reduce renal IRI injury. There is still a lack of a noninvasive and accurate index to evaluate the effect of RIPC in clinical practice.
Goal(s): To evaluate the effect of R2-mapping imaging on remote ischemic preconditioning
Approach: The RIPC model of both lower limbs of experimental rabbits was established, and MRI imaging, hematological detection, renal oxidation and antioxidant indexes were detected respectively 1h and 24h after RIPC
Results: Compared with the control group, the R2 'value of renal medulla in RIPC group was significantly decreased, pO2 and sO2 were increased, SOD activity was increased, and MDA content was decreased.
Impact: To provide a non-invasive MRI technique for quantitative evaluation of RIPC effect in clinic
