Simulation results for BASE as function of eight SNR levels. a-c Variability of absolute and semi-quantitative perfusion measures over myocardial sectors and 20 noise realizations. Reference values from input concentration dynamics are indicated by the solid line. Dotted lines indicate the ±25% interval around the reference value. a Absolute myocardial blood flow (MBF) in [mL / g / min]. For SNR ≥ 20 the values are confined to the ±25% interval. b Myocardial up-slope (SLP). Above SNR = 10 no further improvement of accuracy is apparent. c Area under the curve (AUC). d Mean and standard deviation of absolute MBF quantification over 20 noise realizations per myocardial sector
