Monte Carlo simulated estimates of renal function expressed as differences in renal function between first and second MR renography (MRR) acquisitions using d₁ for the first injection and assuming a total dose of 12 ml (d₂ = 12 ml − d₁). Plots show the simulated changes in renal function: GFR₂ − GFR₁ (A) and RPF₂ − RPF₁ (B) for each combination of doses and for 2 scenarios, a normally functioning kidney and a dysfunctional kidney. In this simulation, the true values of GFR₂ − GFR₁ and RPF₂ − RPF₁ are 0. Error bars denote mean value ± SD.
