A conveníent production of [13N]nitrogen for ventilation studies using a nitrogen gas target for 11C production

Taking advantage of the 14N(p,pn)13N reaction occuring during the 14N(p,α)11C carbon dioxide production, pure [13N]N2 suitable for PET ventilation studies was produced in a standard nitrogen gas target for 11C-production (“carbon-11 target”), after elimination of 11CO2 and short-lived oxygens.
