Vessel Encoded Arterial Spin Labeling using Pseudo-Continuous Tagging

We introduce here an arterial spin labeling method in which groups of vessels can be simultaneously encoded to provide maps of vascular territories with high SNR efficiency. Based on pseudo-continuous tagging, this method uses additional transverse gradient pulses and an RF phase cycling scheme to provide optimal Hadamard encoding of the vessels. In principle, any number of vessels can be encoded and reconstructed to provide vascular territory maps in the same scan time and with the same SNR as a single conventional ASL scan. Examples in the human brain are shown.
