gallium-68 a positron emitter radionuclide, with great impact on the nuclear medicine, has been widely used in positron emission tomography (pet) diagnosis of various malignancies in humans during more recent years especially in neuroendocrine tumors (nets). the vast number of 68ge/68ga related generator productions, targeting molecule design (proteins, antibody fragments, affibodies, peptides ...

Introduction Range and diffusion of positron-emitting radiopharmaceuticals are important parameters for image resolution in positron emission tomography (PET). In this study, GEANT4 toolkit was applied to study positron diffusion in soft tissues with and without a magnetic field for six commonly used isotopes in PET imaging including 11C, 13N, 15O, 18F, 68Ga, and 82Rb. Materials and Methods GEA...
