SAN FRANCISCO--(BUSINESS WIRE)-- Bruker Corporation today announced the introduction of its groundbreaking dissolution Dynamic Nuclear Polarization (d-DNP) Polarizer at the 2025 Hyperpolarized Carbon-13 MRI Technology Development Workshop at the University of California San Francisco (UCSF) Hyperpolarized MRI Technology Resource Center. The first customer installation of this innovative technology has been successfully completed, marking a milestone in hyperpolarized MRI for preclinical research to improve cancer diagnostics and to assess response to treatment.

Dynamic Nuclear Polarization (DNP) can enhance the sensitivity of Nuclear Magnetic Resonance (NMR) and Magnetic Resonance Imaging (MRI) by transferring polarization from electron spins to nuclear spins. Dissolution DNP (d-DNP) extends the applicability of DNP to solution-state liquids NMR and to preclinical MRI research. Polarization occurs in a separate 7 Tesla polarizer magnet at temperatures below 1.4 Kelvin, accelerated by Bruker’s proprietary active cross-polarization technology.

Subsequently, the highly polarized frozen sample is ejected, melts and dissolves, achieving sensitivity gains of over 10,000-fold in solution samples near room or body temperatures, enabling the observation of low-abundance nuclei like ¹³C in real-time. Hyperpolarized MRI using d-DNP is particularly beneficial for in vivo studies of ¹³C-labelled metabolites, enabling live tracking of chemical conversion to downstream metabolites. This highlights metabolic differences between healthy and diseased tissues for conditions ranging from cancer to cardiac health. It can be used to assess response to treatment in animal models, contributing to understanding drug efficacy and disease mechanisms.

With the novel Bruker d-DNP Polarizer, scientists can conduct previously impossible experiments in chemical or metabolic analysis in NMR and preclinical MRI. Bruker provides a faster d-DNP approach using cross polarization (CP) of ¹H and ¹³C. This patented CP provides 5-10x faster polarization compared to traditional d-DNP of ¹³C. This new CP technology is a testament to Bruker's commitment to pushing boundaries and empowering scientists to conduct groundbreaking research.

Professor Renuka Sriram, who leads the preclinical Hyperpolarized Magnetic Resonance Imaging group at UCSF, highlighted the significance: "The Bruker d-DNP Polarizer is a pivotal new tool for our research team. This will enable us to explore metabolic pathways that are only accessible with dissolution DNP. Bruker’s much faster CP-based d-DNP technology and automated d-DNP system further enhance our ability to develop diagnostics for cancers and other metabolic conditions."

Professor Dan Vigneron, Director of the Hyperpolarized Imaging Center at UCSF, elaborated: "With this advanced d-DNP system, we can accelerate our preclinical research efforts and contribute to the development of more effective diagnostic tools. Our collaboration with Bruker is instrumental in pushing the boundaries of what is possible in hyperpolarized MRI."

"At Bruker, we are committed to driving innovation in the field of hyperpolarization," stated Dr. James Kempf, Senior Manager DNP & Hyperpolarization at Bruker BioSpin. "The installation of our d-DNP Polarizer at UCSF exemplifies our dedication to advancing scientific research, and it also highlights our partnerships with leading institutions to develop cutting-edge technologies to transform healthcare."

As the research community begins to harness the capabilities of the Bruker d-DNP Polarizer, the potential for pioneering discoveries in metabolic imaging and disease diagnostics is immense. The collaboration between Bruker and UCSF is set to pave the way for future advancements in hyperpolarized MRI. Additional d-DNP customer installations are already planned in Europe and the US. The UCSF partnership aims to validate the d-DNP technology in oncology applications, including demonstrating the value of the unique higher-throughput cross-polarization d-DNP approach.
