Accumulation, however, was also observed in regions of nonmalignant inflammatory and infectious conditions, including in the musculoskeletal system. The most common radiotracer in use today is 18F-fluorodeoxyglucose (18F-FDG) which is a radiolabelled sugar (glucose) molecule. Imaging with 18F-FDG PET is used to determine sites of abnormal glucose metabolism and can be used to characterize and localize many types of tumours. Answer: Fluorodeoxyglucose is a radiolabeled tracer for imaging brains with positron emission tomography (PET scan). A PET scan is a useful method for imaging the body, and especially the brain. In a PET scan, the patient is given an intravenous injection of a radionuclide, a radioactive compound that emits gamma rays.

Fluorine 18 fluorodeoxyglucose (FDG) positron emission tomography (PET) is commonly performed for staging and restaging of solid tumors.
The aim of the present paper is to systematically review all available literature on preradiotherapy high uptake areas (hotspots) as a potential target for dose escalation in different tumour sites, and to understand the potential role and limitations of fluorodeoxyglucose (FDG)-positron-emission tomography (PET)/computed tomography (CT) in this context.
