Description
ポジトロン放出断層撮影法(PET)は、生存被験者の組織内のポジトロン放出放射性医薬品の濃度を測定するための医療用撮像技術である。サイクロトロンで生成したフッ素−18の放射性核種から調製される放射性医薬品、即ちトレーサ、は、脳、心臓、の研究及び臨床研究のための種々のPET生物学的プローブの中で、及びガンの診断で広い用途を見出してきた。典型的PET処置の中では、放射性医薬品が被験者の血流に投与され、次いで生体内で放射性医薬品から放出されるポジトロン放射能の分布が、時間の関数として放出断層撮影法により測定される。被験者の組織が放射性医薬品と相互に作用するとき、コンピュータによる再構成手法が行なわれて、組織の断層撮影画像が得られる。
(実験結果)
次は、前述の[18F]F2のツー・ショット法の中で、F2/Heウォッシュ・アウト混合物を使用した場合の実験及びその結果の説明である。
