A True simulated input AIF (\({C}_{p}\left(t\right)\); solid grey line) and MDIF (\({C}_{p}^{MDIF}\left(t\right)\); dashed black line) obtained with the SIME algorithm. B Percent difference between MDIF and the true simulated AIF as a function of time. AIF: Arterial input function; MDIF: Model-derived input function; SIME: Simultaneous estimation; VOI: Volume-of-interest; WB: Whole brain
