Hyperpolarized MRI Technology Resource Center

The Hyperpolarized MRI Technology Resource Center (HMTRC)  is a Biomedical Resource Technology Center funded by the National Institute of Biomedical Imaging and Bioengineering (NIBIB) focuses on the development and dissemination of new advances in dissolution DNP techniques and instrumentation, specialized data acquisition methodology, and analysis software for biomedical research. 

Hyperpolarized MR is an emerging molecular imaging method to monitor enzymatic conversions through key, previously-inaccessible biochemical pathways.  Through numerous studies to date, hyperpolarized carbon-13 MR has shown outstanding research and potential clinical value, but requires major technological development to realize its full potential.  This motivation, coupled with the rapidly expanding interest at other sites, compelled us to create the “Hyperpolarized MRI Technology Resource Center”.  

This center is based on three Technology Research & Development (TR&D) projects led by experienced hyperpolarized MR researchers.  TR&D1 is focused on DNP polarizer and MR acquisition development and pre-clinical animal studies.  TR&D2 focuses on the development of new robust and realistic pre-clinical models for HP MR studies, optimization of current HP probes & investigation of new HP probes, and the development of methods that provide appropriate correlative pathologic, biologic and other imaging data for understanding and validating HP MR findings.  TR&D3 focuses on the development of a free open-source specialized data analysis platform for HP MR data reconstruction and interpretation.  All TR&D developments are driven in a push-pull interaction by the independently funded Collaborative Projects and the technology resources of the center are utilized by Service Projects and disseminated to all interested investigators through hands-on workshops, symposia, visits/training, formal courses, and our center website.  

The goal of the HMTRC is to collaboratively develop new technology to advance this field in order to better identify and understand human disease and ultimately to translate and disseminate these techniques for improved healthcare.

Publication #1 Title: Pulse sequence considerations for quantification of pyruvate-to-lactate conversion kPL in hyperpolarized 13C imaging

Authors: Hsin‐Yu Chen  Jeremy W. Gordon  Robert A. Bok  Peng Cao  Cornelius von Morze  Mark van Criekinge Eugene Milshteyn  Lucas Carvajal  Ralph E. Hurd  John Kurhanewicz  Daniel B. Vigneron  Peder E.Z. Larso

Abstract: Hyperpolarized 13C MRI takes advantage of the unprecedented 50 000‐fold signal‐to‐noise ratio enhancement to interrogate cancer metabolism in patients and animals. It can measure the pyruvate‐to‐lactate conversion rate, kPL, a metabolic biomarker of cancer aggressiveness and progression. Therefore, it is crucial to evaluate kPL reliably. In this study, three sequence components and parameters that modulate kPL estimation were identified and investigated in model simulations and through in vivo animal studies using several specifically designed pulse sequences

Publication #2 Title: Hyperpolarized 13C MRI: State of the Art and Future Directions

Abstract: Hyperpolarized (HP) carbon 13 (13C) MRI is an emerging molecular imaging method that allows rapid, noninvasive, and pathway-specific investigation of dynamic metabolic and physiologic processes that were previously inaccessible to imaging. This technique has enabled real-time in vivo investigations of metabolism that are central to a variety of diseases, including cancer, cardiovascular disease, and metabolic diseases of the liver and kidney. This review provides an overview of the methods of hyperpolarization and 13C probes investigated to date in preclinical models of disease. The article then discusses the progress that has been made in translating this technology for clinical investigation. In particular, the potential roles and emerging clinical applications of HP [1-13C]pyruvate MRI will be highlighted. The future directions to enable the adoption of this technology to advance the basic understanding of metabolism, to improve disease diagnosis, and to accelerate treatment assessment are also detailed.
