A, Overview of the non‐time‐encoded pCASL labeling scheme with a label duration of 600 ms and a minimum PLD of 100 ms. For the LL readout 16 phases of 158 ms were acquired with a constant flip‐angle of 10°. Four slices were excited simultaneously by using a simultaneous multi‐slice acquisition to acquire 16 slices. B, Single‐slice example of the ASL data set when using this conventional pCASL labeling resulting in 16 chronological time points. The numbers in the upper right corner indicate the PLDs in milliseconds. After the ninth LL phase, little ASL signal was left for the remaining 7 LL acquisitions to provide sufficient image quality. a.u. = arbitrary units
