Vessel Selective Arterial Spin Labelling allows assessment and quantification of vessel specific perfusion territories. We make use of Parallel Transmission in order to create 'label' and 'no label' regions to selectively label arteries within the neck. An in-silico simulation was performed to assess the specificity of the method in comparison to using a single surface coil when attempting to only label the right side arteries in the human neck. Results show that for an increasing number of coils contralateral labelling of the left side arteries is reduced whilst maintaining high labelling efficiency on the right.
