Fig. 5
Comparison of population-averaged \({AIF}_{\beta }\) to \({AIF}_{DG}\) a and \({AIF}_{SG}\) b. Shaded areas refer to average \({AIF}_{\beta }\) ± standard deviation in the main plots. Insets show early time behaviour and shaded areas refer to average \({AIF}_{DG}\) ± standard deviation and \({AIF}_{SG}\) ± standard deviation. Measurement data points have been decreased in the plots for better visualisation of the standard deviation bands
