Quasi-continuous production of highly hyperpolarized carbon-13 contrast agents every 15 seconds within an MRI system

Magnetic resonance imaging of hyperpolarized contrast agents has enabled unprecedented imaging capabilities in a biomedical setting, but its widespread application is hindered by the time and costs associated with preparing hyperpolarized carbon-13 samples. Here, the authors demonstrate virtually-continuous production of batches of highly-hyperpolarized carbon-13 contrast agents every 15 s within an MRI system without a stand-alone polarizer.
