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.
