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.
In the United States, a PET scan is estimated to be US$1500-$5000. In England, the National Health Service reference cost (2015–2016) for an adult outpatient PET scan is £798. [93] In Australia, as of July 2018, the Medicare Benefits Schedule Fee for whole body FDG PET ranges from A$953 to A$999, depending on the indication for the scan. [94]
3-dimensional [18 F]FDG-PET image with 3D ROI generated by a threshold based algorithm.The blue dot in the MIP image bottom right marks the maximum SUV within the ROI.. The standardized uptake value (SUV) is a nuclear medicine term, used in positron emission tomography (PET) as well as in modern calibrated single photon emission tomography (SPECT) imaging for a semiquantitative analysis.

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.
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]
PET imaging with 18F-FDG takes advantage of the fact that the brain is normally a rapid user of glucose. Standard 18F-FDG PET of the brain measures regional glucose use and can be used in neuropathological diagnosis. Example: Brain pathologies such as Alzheimer's disease greatly decrease brain metabolism of both glucose and oxygen in tandem ...
A Human-Derived, Genetic, Positron-emitting and Fluorescent (HD-GPF) reporter system uses a human protein, PSMA and non-immunogenic, and a small molecule that is positron-emitting (18 F) and fluorescent for dual modality PET and fluorescence imaging of genome modified cells, e.g. cancer, CRISPR/Cas9, or CAR T-cells, in an entire mouse.

In PET scanning, a radioactive, biologically active substance, most often 18 F-FDG, is injected into a patient and the radiation emitted by the patient is detected to produce multiplanar images of the body. Metabolically more active tissues, such as cancer, concentrate the active substance more than normal tissues.
