We found that a prototype thin-slab stack-of-stars QISS sequence using a low-flip-angle FLASH readout can be used for whole-neck arterial evaluation in under 7 minutes. The technique minimizes flow-related saturation effects similarly to 2D QISS, while providing greater scan efficiency compared with 3D TOF and much improved image quality and through-plane spatial resolution compared with 2D TOF.
