Radiopharmacy and cyclotron networks

The factories and courier routes that make and deliver short-lived radioactive tracers to hospitals within hours.

PET tracers (18F, half-life 110 minutes) are produced in regional cyclotron pharmacies and driven or flown to scanners the same day; 68Ga comes from generators or cyclotrons on site; 177Lu and 225Ac therapies are made centrally and shipped globally against decay. Networks: PETNET (Siemens), Cardinal Health, SOFIE, Curium, Jubilant Radiopharma, Isologic/Isorad in Canada, with regional players in Europe and Asia. Capacity and licensing of nuclear pharmacies limits where radioligand therapy can be given.

How it works

Cyclotron proton bombardment or generator elution produces the isotope; automated synthesis modules label the ligand; QC release within an hour; timed logistics deliver a calibrated activity.

Strengths
  • Same-day supply of 18F tracers across most high-income regions
  • Established GMP frameworks
Limitations
  • Rural and low-income coverage gaps
  • Therapy isotope logistics against decay
  • Single points of failure in reactor supply
