Oxygen-15 is a positron-emitting radionuclide with an extremely short half-life of approximately 122 seconds, which is utilized in medical PET imaging to measure cerebral blood flow.
Explain why a hospital must have an on-site cyclotron to synthesize Oxygen-15 immediately prior to patient administration, rather than transporting it from an external commercial production facility.
