Arterial input functions (AIFs) derived from 3D MRXCAT simulations for different undersampling factors and signal intensity errors. AIFs from reconstructions using (a) k-t PCA and (b) k-t SPARSE-SENSE for fully sampled reference, and undersampling factors R = 2, 5, 10. Baseline (dashed red) and upslope limits (solid blue) are indicated in (a,b). c Zoom of the AIF baselines in (a), (b) as indicated by the dashed boxes. d-f Percentage error as a function of the undersampling factor in (d) baseline, (e) upslope and (f) peak signal. Error bars indicate mean and twice the standard deviation across 10 realizations of the simulation
