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 ...

PET (positron emission tomography) is a powerful imaging technique that can provide quantitative information on the distribution of positron emitter labeled radiopharmaceuticals (PET radiopharmaceuticals) in the body. Positrons (ß+) are positively charged beta particles. They are emitted when the atom is proton rich. A positron has only a transient existence. After losing all of its kinetic ene...

PET (Positron Emission Tomography) is a powerful imaging technique through which quantitative information on the distribution of positron emitter labeled radiopharmaceuticals (PET radiopharmaceuticals) in the body can be realized. Positrons (β +) are positively charged beta particles. They are emitted when the atom is proton enriched. A positron has only a transient existence. After losing all ...

Background Fast implementation of positron emission tomography (PET) into clinical and preclinical studies highly demands automated synthesis for the preparation of PET radiopharmaceuticals in a safe and reproducible manner. The aim of this study was to develop automated synthesis methods for these six 18F-labeled radiopharmaceuticals produced on a routine basis at the University of Pennsylvani...

Nuclear medicine techniques (single photon emission computerized tomography, SPECT, and positron emission tomography, PET) represent molecular imaging tools, able to provide in vivo biomarkers of different diseases. To investigate brain tumours and metastases many different radiopharmaceuticals imaged by SPECT and PET can be used. In this review the main and most promising radiopharmaceuticals ...

After reading Part IV of this series of nuclear cardiology articles, the reader should be able to describe: (a) the differences between SPECT and PET techniques; (b) the various radiopharmaceuticals and imaging protocols used for detecting viability with SPECT; (c) the different radiopharmaceuticals and imaging protocols used for detecting viability with PET; and (d) the imaging patterns observ...

References .......................................................................... 27 Abstract The vast majority of PET radiopharmaceuticals today are cyclotron produced. Carbon-11 (C), Nitrogen-13 (N), Oxygen-15 (O) products are created for in-house use only due to their short half-lives. The longer half-life of Fluorine-18 means that F-labeled PET radiotracers can be widely distributed. Pr...
