[Automated synthesis system for production of 11C-glucose]

A fully automated synthesis system of 11C-glucose by the photosynthesis method has been developed for clinical use. This system has been designed to be as convenient as possible for routine use, and the full automation of the whole procedure from the target gas recovery to collection of the final 11C-glucose/fructose mixture has been accomplished by microcomputer control. A mixture of 11C-glucose/fructose (1:1) was obtained with 20 approximately 35% of radiochemical yield within 60 min.
