Resumo: |
The gallium-68 (68Ga), an extremely promising positron-emitting radionuclide, has major advantages when compared to other radionuclides used in Positron Emission Tomography (PET), like fluor-18 and carbon-11. Differently from these PET radionuclides, gallium-68 is available from a 68Ge/68Ga generator, which allows its distribution even in nuclear medicine centers located far from cyclotrons. In recent years, an increase in the use of 68Ga PET radiopharmacy was observed around the world. However, in Brazil there is still only four centers with this technology available, mainly due to the difficulty in the access. Radiopharmaceuticals used for diagnostics are scarcely accessible in our country. Among radiopharmaceuticals most used around the world are the DOTA-peptides, somatostatin analogs for the diagnosis of neuroendocrine tumors. Considering the present scenario, this study aimed to develop a diagnostic kit of DOTA-TOC for labeling with 68Ga, with high radiolabeling yield and high radiochemical purity, thus stimulating the use of this innovative radionuclide in Brazil. |
