Multi-parametric MRI techniques may allow the assessment of renal injury and function in a sensitive and objective manner. This study aimed to evaluate an array of MRI methods that exploit endogenous contrasts for their sensitivity in detecting abnormal features associated with kidney disease in a murine model of unilateral ureter obstruction (UUO). Diffusion weighted imaging (DWI), quantitative magnetization transfer (qMT), chemical exchange saturation transfer (CEST), and nuclear Overhauser enhancement (NOE) provide specific information about the cellular and molecular changes produced by UUO.
