| Research Abstract |
The purpose of this study was to explore the feasibility of carbon-13(^<13> C) magnetic resonance imaging(^<13> C-MRI) to depict^<13> C-labeled amyloid-binding materials in model mice for Alzheimer dementia at 7T. Although we succeeded in producing^<13> C-labeled amyloid-binding materials, water solubility of the materials was low. We tried to solve the materials. After administration of the materials to the model mice, C-13 MR imaging of the brain was performed. Although the area of high signal in the brain was observed, there were some discrepancies between the MR and histopathologic findings. Further investigation is needed to clarify the feasibility of^<13> C-MRI.
