Impact of standard versus super-resolution reconstruction on quantitative arterial metrics for QISS MRA. Super-resolution reconstruction resulted in statistically significant increases in arterial-to-background contrast-to-noise ratio (CNR), arterial-to-background contrast and arterial sharpness, and a significant reduction in arterial full-width-at-half-maximum. Plots show data from all QISS implementations irrespective of the k-space trajectory, acquired spatial resolution, number of imaging shots, and use of physiologic triggering. Legends refer to segments of the middle cerebral artery. Blue and dashed lines are the lines of robust regression and unity, respectively.
