| Outline of Final Research Achievements |
The purpose of this study was to build a technological basis for real-time molecular imaging that can be applied to metabolic processes that require time for distribution and metabolism by room temperature dynamic nuclear polarization MRI (DNP-MRI). To this end, we have developed a DNP-MRI probe that can measure other nuclei such as 13C. As a result, it was indicated that 13C DNP-MRI can be performed in a practical time. In addition, it was applied to a tumor or diabetes model of anima. The above results suggest the potential effectiveness as metabolic imaging of 13C DNP-MRI.

| Academic Significance and Societal Importance of the Research Achievements |
様々な代謝反応により生体機能・恒常性が調節されている。そのため、疾患状態において代謝反応や代謝産物が変化し、診断や治療効果の判断指標として用いられている。リアルタイムで臓器代謝活性を計測できれば、創薬・医療に貢献することが期待できる。極低温核偏極MRIは近年発展している技術であり、前立腺がん等での代謝変化検出が示されているが、測定可能時間が短く応用が限られている。そこで、常温で繰り返し計測を実現し応用範囲を広げることを目的とし、本研究ではその技術基盤を確立した。
