Radiochemistry/Cyclotron Services


The Radiochemistry and Cyclotron Facility produces radioactive targeting molecules for PET imaging studies. Services offered:

  • We produce a menu of PET tracers which are not commercially available.
  • We perform custom syntheses of novel PET tracers
  • Our on-site cyclotron allows production on demand of PET radionuclides 18F, 11C, and 13N
  • The PET radionuclides 64Cu, 89Zr, and 124I are also available from third party vendors
  • 99mTc SPECT tracers are also available


The most commonly used PET radionuclides are 18F and 11C, which are produced on site. Longer lived 64Cu, 89Zr, and 124I, available every 1-2 weeks, are better matched to the longer uptake and residence times of higher molecular weight PET probes such as antibodies, peptides, and nanoparticles.
