Enhancing Biomedical Imaging Through Hyperpolarized
Magnetic Resonance

The work presented here will detail recent developments in two such systems: (1) hyperpolarized xenon gas, and (2) hyperpolarized silicon micro- and nanoparticles. Hyperpolarized 129Xe is produced through spin-exchange optical pumping, and can be used for material surface studies, molecular biosensing, and clinical pulmonary imaging. Hyperpolarized 29Si particles are produced using dynamic nuclear polarization, and are currently being developed for targeted molecular imaging of different diseases. These systems, along with metabolic imaging of 13C-labelled contrast agents, are under various stages of development and translation to the clinic, where they will have the potential to positively impact the lives of patients through early diagnosis, active surveillance, treatment efficacy monitoring, and identifying disease recurrence.
