   Whole-body PET scan using 18 F-FDG (fluorodeoxyglucose). The normal brain and kidneys are labeled, and radioactive urine from breakdown of the FDG is seen in the bladder. In addition, a large metastatic tumor mass from colon cancer is seen in the liver. PET scanning with the radiotracer [18 F]fluorodeoxyglucose (FDG) is widely used in clinical ...

   en.wikipedia.org/wiki/PET-CT

   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 is often conducted by having the person consume a drink that includes radioactive isotopes or by having the isotopes injected into a person's bloodstream. These isotopes are absorbed by different tissues in the body, including malignant tumour cells, and PET imaging can visualize the function or detect tumour cells by visualizing how the ...

5. PET radiotracer - Wikipedia

   en.wikipedia.org/wiki/PET_radiotracer

   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.

   As a result, FDG-PET can be used for diagnosis, staging, and monitoring treatment of cancers, [21] particularly in Hodgkin's disease, non-Hodgkin lymphoma, colorectal cancer, breast cancer, melanoma, and lung cancer. It has also been approved for use in diagnosing Alzheimer's disease. [citation needed]
