A type-1 STZ induced diabetic nephropathy rat model is investigated with hyperpolarized [1- 13C]pyruvate, to allow early diagnosis and monitoring of decreased kidney function, with increased diabetes. We here show the metablic profile of the type 1 diabetic rat, from early diabetes to late diabetes, with a significant altered profile over the time course, showing the decreasing kidney function. The method show great promise for accurate non-invasive metabolic profiling of diabetic patients, with different stages of reduced kidney function.
