We achieved in-vivo high-resolution sodium MR imaging and measured sodium concentrations of rabbit kidneys at 3T human scanner using a high-sensitive dual-tuned RF coil and ultra-short echo time spiral sequence. Non-invasive assessment of alteration of corticomedullary sodium gradient may serve as an early indicator of renal pathology.
