Is the information provided by amino acid PET radiopharmaceuticals clinically equivalent in gliomas?
Ectopic ACTH syndrome caused by excessive production of adrenocorticotropic hormone (ACTH) a neuroendocrine tumor (NET) is an extremely rare disease, the main manifestation which pronounced hypercortisolism. In order to avoid development life-threatening complications and disability patient, timely topical diagnosis rapid decision-making on further management tactics are necessary. The problem ...
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...
Introduction Positron emission tomography (PET) tracers has the potential to revolutionize cancer imaging and diagnosis. PET tracers offer non-invasive quantitative imaging in biotechnology and biomedical applications, but it requires radioisotopes as radioactive imaging tracers or radiopharmaceuticals. Method This paper reports the synthesis of 18F-nGO-PEG by covalently functionalizing PEG w...
