Hyperpolarized [1-13C]pyruvate was used in this study to explorer the capability of detecting ischemic injury in the kidneys and to present the heterogeneity from the different kidney compartments. This was done using Michaelis–Menten kinetics by obtaining data in the an saturation recovery setup. Ischemic injuries was observed and in close correlation to standard perfusion MRI. The results from this study shows promise for the human introduction of this method.
