The promising imaging technique of chemical exchange saturation transfer (CEST) MRI, which is sensitive to microenvironment properties including pH, metabolites, temperature, metal ions, and enzymatic activities, has been increasingly applied in vivo such as acute ischemia, infection and cancer. The aim of this work was to observe the differentiation between normal and acute kidney injury (AKI) using echo-planar imaging sequence (EPI) as well as the sensitive ratiometric methods under 7T magnetic field.
