Cardiac phosphorus (³¹P) magnetic resonance spectroscopy (MRS) offers unique insights into the metabolism of the human heart. To further improve cardiac ³¹P MRS acquisitions, the implementation of a proton (¹H) magnetic resonance imaging (MRI) navigator into a ³¹P MRS pulse sequence using multinuclear interleaving is demonstrated. In this feasibility study we further apply a method to robustly detect the heart on low-resolution navigator images. Combined with multinuclear interleaving this facilitates time-efficient position updates of the ³¹P MRS voxel to prospectively correct for respiratory motion.
