3D SPGR is commonly used clinically for contrast-enhanced body imaging, but requires time for a gradient spoiler every TR. This consumes up to 40% of scan time, even for a non-cartesian trajectories with relatively long readouts, such as cones. Removing the spoiler can save time but causes severe artifacts. In this study, we propose a novel approach of applying interleaved, randomized spoilers to a motion-robust 3D-cones sequence. The feasibility of the approach to shorten acquisition time without introducing image artifacts was validated on both healthy subjects and patients.
