A prospective, randomized, blinded study was performed to compare the efficacy of two protective interventions (administration of loop diuretic furosemide and antioxidant n-acetyl cysteine (NAC)) in a rat model of contrast-induced nephropathy (CIN). Studies were performed with three different contrast media. Our data with BOLD MRI measurements show that diuretic furosemide resulted in reduced enhancement in R2* post-contrast media while NAC resulted in no appreciable change compared to the control group. Further studies to confirm that the reduced hypoxia leads to reduced CIN with additional direct markers or renal injury are necessary.
