Outline of Final Research Achievements

This study aimed to develop radiosynthetic methods of [18F]Fluoroacetate ([18F]FACE) derivatives, Methyl [18F]Face, Ethyl [18F]Face and Benzyl [18F]FACE, which are supposed to have enhanced transferability to the brain and retention to the damaged area in order to pursue a new diagnostic imaging tracer evaluating ischemic brain injury. Among these, Methyl [18F]FACE showed the highest in-vivo stability, so we evaluated the utility of Methyl [18F]FACE using experimental rats settled under a transient cerebral ischemia by MCA occlusion and reperfusion state. Methyl [18F]FACE showed apparently higher accumulated in the ischemic region during MCA occlusion than in the contralateral healthy side. It was suggested that Methyl [18F]FACE is an optimal tracer for imaging of brain ischemia.

Academic Significance and Societal Importance of the Research Achievements

脳血管障害の重症度評価、治療方針の決定、治療効果判定などの目的で使用される[15O]ガス ([15O]CO、[15O]O2、[15O]CO2)は、検査を行えるPET施設が少なく、動脈採血を基本とする非侵襲的な検査である。一方、新規に開発した18F標識新規酢酸誘導体は、半減期が長く実用的で検査数を増やすことが可能となり、将来的には、現在よりも質の高い脳核医学PET検査が広く一般診療で利用されるようになると期待される。
