11C-MET-PET versus 18F-FET-PET
• Despite the considerable number of encouraging results, the application of MET-PET in diagnosis of brain tumors has been mainly limited to a small number of centers. The short physical half-life of carbon-11 (20 min) necessitates an on-site cyclotron for MET-PET examination, making the utilization of this tracer for the PET investigation difficult.
• In contrast to MET the physical half time for 18F of 110 minutes allows performing the FET-PET studies in centers without an on-site cyclotron.
