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. Different tracers are used for various imaging ...
Positron emission tomography–computed tomography (better known as PET-CT or PET/CT) is a nuclear medicine technique which combines, in a single gantry, a positron emission tomography (PET) scanner and an x-ray computed tomography (CT) scanner, to acquire sequential images from both devices in the same session, which are combined into a single superposed (co-registered) image.
Cardiac PET (or cardiac positron emission tomography) is a form of diagnostic imaging in which the presence of heart disease is evaluated using a PET scanner. Intravenous injection of a radiotracer is performed as part of the scan. Commonly used radiotracers are Rubidium-82, Nitrogen-13 ammonia and Oxygen-15 water. [1]
Positron emission tomography (PET) is a nuclear medicine imaging methodology that tracks positron emitting radioisotopes. [20] PET enables visual image analysis of multiple different metabolic chemical processes and is thus one of the most flexible imaging technologies.
One of the most popular uses of radiofluorination is its application in PET scans. Positron emission tomography (PET) is a widely used imaging technique in the field of nuclear medicine. [1] [5] With applications in research and in diagnosis, a PET scan can be used to image tumors, diagnose brain disease, and monitor brain or heart function [8 ...
Positron emission tomography (PET) uses coincidence detection to image functional processes. Short-lived positron emitting isotope, such as 18 F, is incorporated with an organic substance such as glucose, creating F18-fluorodeoxyglucose, which can be used as a marker of metabolic utilization. Images of activity distribution throughout the body ...
Four years later, through a clinical trial, John Perrygo was diagnosed with Alzheimer's disease thanks to a positron emission tomography scan (PET) that wasn't yet available to the general public.
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.
