  • Abstract
  • Look Inside

 It has been still debatable if 11C-labeled carbon dioxide could be used in conjunction with positron emission tomography (PET) as an acid-base or metabolic tracer. Recently we found that dynamic PET with 11CO2 showed different dynamic images with time. In order to get some information about a biochemical basis of dynamic PET with 11CO2, we performed an experimental study on 11CO2 metabolism in rats with our special attention to 11CO2 fixation.

 A Wistar rat (200~300 g) in a glass container was exposed to 11CO2 air (50~100 mCi) for 5 minutes and sacrificed soon or 20 minutes later.
