| Outline of Final Research Achievements |
Brain amyloid PET plays an important role in detection of in vivo amyloid-beta (Aβ) plaque deposition as a biomarker of Alzheimer's disease (AD). Quantitative analysis of amyloid PET has been widely performed to accurately measure amyloid deposition, especially in clinical research and trial. However, an individual high-resolution MRI was required for amyloid PET quantification process. Therefore, we developed a PET-only amyloid quantification method in this study.
The research findings were published in academic journals and we applied for Japan and US patents.

| Academic Significance and Societal Importance of the Research Achievements |
これまではMRIの撮像や高価な画像処理ソフトウェアが必要であったアミロイドPETの定量評価が、MRIなしで簡便に安価で実施できるようになります。その結果、アミロイドPETの読影補助や経時的変化の評価が研究や診療において広く実施できるようになります。ひいては、アルツハイマー病等の認知症の研究、診療、治療薬開発の促進につながると期待されます。
