Magnetic resonance imaging (MRI) is a foundational tool in clinical diagnostics with the ability to produce detailed, non-invasive images of internal anatomy and function. Over 100 million scans are performed annually, and the market is projected to reach $10.3 billion by 2030 . However, current MRI techniques face significant limitations in chemically selective metabolic imaging. Sensitivity is often too low to detect key metabolites at physiological concentrations, and strong background signals from water and fat obscure molecular details. Competing modalities such as CT and PET can provide metabolic information, but they rely on ionizing radiation, offer limited chemical specificity, and lack anatomical detail.
Researchers at the University of Florida have developed a continuous-flow system for generating hyperpolarized metabolites using parahydrogen-induced polarization (PHIP). It leverages parahydrogen as a source of nuclear spin order, amplifying MRI signal strength and enabling real-time, chemically selective imaging of metabolic processes. Unlike traditional batch-based hyperpolarization methods, the continuous-flow approach sustains production and delivery of hyperpolarized agents, supporting extended imaging sessions and improved diagnostic accuracy. By overcoming key barriers in sensitivity, workflow efficiency, and patient safety, this technology offers transformative potential for clinical and research applications.
A device for continuous-flow parahydrogen-induced hyperpolarization of metabolites in aqueous solution for advanced metabolic MRI
This technology integrates a continuous-flow hydrogenation reactor with parahydrogen-induced polarization, allowing for the rapid and sustained generation of hyperpolarized metabolites in aqueous solution. By combining a spin order transfer device and advanced membrane-based separation, the system efficiently produces purified imaging agents, overcoming the limitations of batch-based methods and enabling real-time, high-sensitivity metabolic imaging with MRI. The modular design supports seamless integration into clinical workflows and ensures rapid extraction and purification, delivering hyperpolarized agents in seconds and facilitating extended imaging sessions for improved diagnostic precision.
