Sodium is a pivotal metabolite in the equilibrium cell state, and is therefore an ideal candidate as a biomarker for macroscopic damage, which is directly linked to the cellular alterations in the sodium gradient across the cell membrane. We here show the use of a simple relaxometry method for gaining additional insight in ex vivo organs. We show that it is possible to differentiate the healthy kidney from the diseased by 23Na-multi-component relaxation analysis.
