Selective arterial spin labeling (SASL) allows mapping of the perfusion territories in the brain from specific feeding arteries. Interactively designed two-dimensional RF pulses are used to label the selected artery in place of slab-selective pulses used in standard pulsed-ASL techniques. {Figure 1} shows the label profile used for the left and right internal carotid arteries (ICA) and the read-out slice positions. {Figure 2} shows the baseline EPI and perfusion images for the top four slices demonstrating good discrimination of each ICA perfusion territory.
