Abstract: Objectives Ga-68-Dotatoc has become the PET radiopharmaceutical of choice for the diagnosis and treatment follow-up of neuroendocrine tumours. Ga-68-Dotatoc is prepared on-site through a so-called magisterial preparation. The use of an appropriate buffer during the radiolabelling step is essential to maximize the labelling yield and the specific activity. Such a buffer should be nontoxic, able to buffer in the pH range of 3.5-5.0, not compete with gallium ions and preferentially have a weak metal complexing capacity to avoid the formation of colloidal gallium. In addition, the buffer should be allowed for human use. In view of the high radiation dose to the operator when manually handling Ga-68, especially to the extremities, we also tested the buffers in a semi-automated system.
