Ⅰ．はじめに
　ポジトロン放出核種を使った生体の断層撮像（positron emission tomography：PET）における技術開発は，放射性同位元素の製造と標識合成技術，放射線計測技術や画像再構成法，さらに高度な画像解析法の開発などの，多分野の研究者と医学者との協力のもとに実用化がなされてきた．PETは，現在の多様な医療の中で，不可欠な診断技術と位置付けられており，分野横断的なコラボレーションに支えられながら，さらなる技術革新が進んでいるところである．本稿では，PETを使った種々の脳機能画像がどのように開発されてきたかを振り返り，そこからPETの新たな可能性を探るとともに，今後のあり方についても言及したい．
