Figure 2.

The standard deviation of the set of CBF estimates ${\{{\widehat{f}}_{i,k}\}}_{i=1,k=1}^{1000,100}$ for 5‐minute combinations of a (A) single‐PLD (B) free‐lunch time‐encoded (te‐FL) and (C) equidistant multi‐PLD PCASL experiment with supporting experiments to estimate α and $T_{1b}$. The standard deviations linked to the single‐PLD, te‐FL, and multi‐PLD protocols without supporting measurements are highlighted with black boxes, while the protocols with the lowest standard deviation in each ASL modality are highlighted with a red box
