title: Cyclotrons, radionuclides, precursors, and demands for routine versus research compounds.
abstract: Accelerators for producing commonly used short-lived positron emitters for positron emission tomography are addressed in the context of their use for the preparation of labeled compounds for research and routine biomedical applications. Progress and direction in the preparation and use of radiotracers for studies of the brain are discussed. Advancement to complete automation is stressed as an important factor for the eventual use of positron emission tomography as a routine clinical tool in universities and major medical centers.
