  • Hyperpolarized magnetic resonance imaging (MRI) has the potential to revolutionize MRI applications, but requires large and clumsy instruments. Here, the authors present a 0.5 T benchtop system that allows to hyperpolarize, image, and spy on nuclear spins like 13C within seconds.

  • Current efforts to enhance NMR signals using the signal amplification by reversible exchange (SABRE) focus on optimizing polarization transfer from parahydrogen-derived hydride ligands to the substrate, but this requires quantitative information on ligand exchange rates, which common NMR techniques struggle to provide. Here, the authors introduce an experimental spin order transfer sequence with readout occurring at hyperpolarization-enhanced 15N nuclei that are directly interacting with the SABRE catalyst, enabling robust evaluation of ligand chemical exchange.
