| Outline of Final Research Achievements |
In a field of molecular imaging research, progress has been made for each modality such as PET, SPECT and MRI, but a potential of combining these modalities has not been studied well. Therefore, this work aimed at realization of combined PET/SPECR/MRI for small animals. Challenges made in this work were the realization of a Compton-PET system and the development of a compact depth-of-interaction (DOI) type detector.

| Academic Significance and Societal Importance of the Research Achievements |
PET、SPECTおよびMRIの同時撮像が出来れば、高精細MRI画像に、複数のトレーサーによる生体内分子動態情報（血流、エネルギー代謝、レセプター、伝達物質等）の完全同時評価が加わるようになる。例えば、脳血流変化と神経活動の関連付けや、再生治療細胞の生体内位置と治療効果の同時取得など、特異的な生体機能を多角的に評価することが可能になり、サル等を使った賦活実験で脳機能の解明や薬物動態イメージングによる創薬研究の推進が期待される。
