The most common PET scan uses fluorodeoxyglucose (FDG) as the tracer in order to show how glucose concentrations change in tissue over time — a proxy for metabolic activity. (sciencemag.org)
For this research, a total of 28 subjects were imaged with a variety of imaging modalities, including standard imaging with computed tomography, magnetic resonance imaging and molecular bone scan (SI); PET with a common radiotracer called fluorodeoxyglucose (FDG - PET); and PET with computed tomography and the agent Zr - 89 IAB2M (IAB2M PET / CT) assessed in escalated doses.

To measure brain glucose metabolism, researchers used a specialized imaging technique called 18F - fluorodeoxyglucose positron emission tomography (FDG - PET). (sciencedaily.com)
