| Outline of Final Research Achievements |
Nuclear magnetic resonance (imaging) (NMR/MRI) is a technique which uses a radio frequency pulse as a principle for the excitation/relaxation of nuclear spins, and widely used not only the determination of the molecular structure of compounds, but also the noninvasive imaging deep part of the body. However, "the low sensitivity" is a fundamental and the greatest drawback of this technique. To address these issues, new imaging methodologies, such as dynamic nuclear polarization (DNP) or chemical exchange saturation transfer (CEST), have recently been emerged. In the present study, generation and application of brand-new MR probes that allow in situ monitoring of the oxygen molecule release from hemoglobin with high sensitivity were conducted.
