The short-lived effect of hyperpolarization of 13 C poses severe challenges to develop rapid and robust imaging techniques. The concentric rings trajectory is such a technique for 13 C spectroscopic imaging because 1) it is as twice efficient as Cartesian trajectory; 2) it exhibits robustness to minor system imperfections; 3) it retains the ability of variable density and good parallel imaging properties; 4) and it is insusceptible to pulsatile flow artifacts. Preclinical studies have been performed for evaluation. Concentric rings trajectory shows great potential to be applied for accelerated hyperpolarized 13 C MRSI.
