We evaluated whether super-resolution reconstruction could be used to improve the vascular detail of quiescent-interval slice-selective (QISS) MRA of the intracranial circulation. Results suggest that super-resolution reconstruction can substantially improve intracranial arterial delineation without the signal-to-noise ratio penalty of directly acquiring thin-slice images.
