Production of 17F (t1/2=65 s) in the form of [17F] F2 has been achieved using both the 20Ne(p,alpha)17F and 16O(d,n)17F reactions with 11 MeV protons and 6 MeV deuterons, respectively. Yields have proven suitable for subsequent radiosynthesis of the blood flow tracer, [17F]CH3F (>60 mCi in saline), currently in use for fast repetition human studies of regional cerebral blood flow with positron emission tomography. Thick target yields of 15 mCi /microA for protons and 44 mCi/microA for deuterons have been measured for [17F]F2.
