Brief Summary

Multimodal functional magnetic resonance (MR) methods, including MR diffusion, Blood-Oxygenation Level Dependent (BOLD) imaging and MR spectroscopy may provide complementary information about the functional status of a kidney. The researchers hypothesize that these non-invasive methods correlate with histology as "gold standard" and compete favorably with conventional in part invasive evaluation methods, and thus provide specific and early detection of kidney diseases of various etiologies, drug toxicity, or renal allograft dysfunction.
