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.
In addition, nuclear medicine scans differ from radiology, as the emphasis is not on imaging anatomy, but on the function. For such reason, it is called a physiological imaging modality. Single photon emission computed tomography (SPECT) and positron emission tomography (PET) scans are the two most common imaging modalities in nuclear medicine. [3]
PET radiotracer is a type of radioligand that is used for the diagnostic purposes via positron emission tomography imaging technique. [1] [2] Mechanism
Positron emission tomography (PET) imaging in theranostics provides insight into metabolic and molecular processes within the body. The PET scanner detects photons and creates three-dimensional images that enable visualization and quantification of physiological and biochemical processes. [ 11 ]
PET response criteria in solid tumors (PERCIST) is a set of rules that define when tumors in cancer patients improve ("respond"), stay the same ("stabilize"), or worsen ("progress") during treatment, using positron emission tomography (PET). The criteria were published in May 2009 in the Journal of Nuclear Medicine (JNM). [1]
Phelps' initial work dealt with the application of basic nuclear physics, chemistry, and mathematics to biomedical imaging. He combined a number of original insights in developing PET: First, he recognized that positron decay provides the opportunity for a unique coincidence detection system, with opposing detectors.
