Chemical exchange saturation transfer (CEST) and magnetization transfer (MT) imaging are sensitive to small molecules with exchangeable protons and macromolecules, respectively. Such methods could complement the physiological information obtained from conventional assays of kidney function and facilitate our understanding of pathological mechanisms in kidney disease. In this study, we used CEST and MT to assess mouse kidney following unilateral ureter obstruction (UUO) to determine if these methods are sensitive to the associated pathology.
