Summary of portion of simulated noise analysis results demonstrating flow estimates derived from distributed model (A) and three-compartment model (B). Presents parameter estimation errors for solely the error introduced by noise levels and limited temporal resolution (assumes model is perfect in the mean). Model solutions were evaluated for three flow states (flow = 0.8, 1.6, 2.4 mL/g/minute) for several count rates. Noise causes greater variance in distributed model estimates than in the compartmental model estimates (markers plotted with horizontal jitter for visualization).
