This is a list of positron emission tomography (PET) radiotracers. These are chemical compounds in which one or more atoms have been replaced by a short-lived, positron emitting radioisotope. Cardiology
PET is a functional imaging technique that produces a three-dimensional image of functional processes in the body. The system detects pairs of gamma rays emitted indirectly by a positron -emitting radionuclide ( tracer ), which is introduced into the body on a biologically active molecule.
Positron emission tomography (PET) [1] is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption.
Brain positron emission tomography is a form of positron emission tomography (PET) that is used to measure brain metabolism and the distribution of exogenous radiolabeled chemical agents throughout the brain. PET measures emissions from radioactively labeled metabolically active chemicals that have been injected into the bloodstream.
In PET imaging, [18 F]FDG is primarily used for imaging tumors in oncology, where a static [18 F]FDG PET scan is performed and the tumor [18 F]FDG uptake is analyzed in terms of Standardized Uptake Value (SUV). FDG PET/CT can be used for the assessment of glucose metabolism in the heart and the brain.
Fluoroethyl-l-tyrosine (18 F) commonly known as [18 F]FET, is a radiopharmaceutical tracer used in positron emission tomography (PET) imaging.This synthetic amino acid, labeled with the radioactive isotope fluorine-18, is a valuable radiopharmaceutical tracer for use in neuro-oncology for diagnosing, planning treatment, and following up on brain tumors such as gliomas.
For clinical PET/CT diagnostics, an activity in the range of 80–150 MBq 68 Ga-Trivehexin is injected intravenously (i.v.). [27] [28] The tracer then distributes with the blood flow and moves into tissues by diffusion, where it specifically binds to its target αvβ6-integrin, while an excess is excreted via the kidneys and the urine.
11C-UCB-J is a PET tracer for imaging the synaptic vesicle glycoprotein 2A in the human brain. [1] It is used to study the brain changes associated with several diseases including Alzheimer's disease, [2] [3] schizophrenia, [4] [5] and depression. [6]
