Real time, free breathing, T2*-weighted (BOLD) images of the kidneys were retrospectively motion corrected and analyzed for physiologic spectral energies. Following induced diuresis a corresponding decrease in cardiac BOLD signal frequency energy was observed in the renal cortex. We hypothesize this corresponds to a decrease in O2 utilization due to decreased renal H2O reabsorption.
