A simple and reliable system for the single-breath inhalation and for short-term rebreathing of radioactive gases used in positron emission tomography is described. It comprises a collection- and radioactivity measurement-device, an inhalation bag for single-breath application, a modified anaesthetic system for rebreathing and a patient exhaled gas management system. The system is mainly used with 15O-labelled gases, but allows also the use of longer lived tracers such as methyl fluoride labelled with 18F or 11C.
本文描述了一种用于正电子发射断层扫描中放射性气体单呼吸吸入和短期再呼吸的简单可靠系统。它包括一个收集和放射性测量装置、一个用于单呼吸应用的吸入袋、一个用于再呼吸的改良麻醉系统和一个患者呼出气体管理系统。该系统主要用于15O标记的气体,但也允许使用寿命更长的示踪剂,如18F或11C标记的氟甲烷。
