PET scanning does this by using radiolabelled molecular probes that have different rates of uptake depending on the type and function of tissue involved. Regional tracer uptake in various anatomic structures can be visualized and relatively quantified in terms of injected positron emitter within a PET scan. [citation needed]
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.

Brain positron emission tomography is a form of positron emission tomography (PET) that is used to measure brain metabolism and the distribution of exogenous radiolabeled chemical agents throughout the brain. PET measures emissions from radioactively labeled metabolically active chemicals that have been injected into the bloodstream.
Shown above is a PET scan of hypermetabolic Astrocytoma in the brain. Many different illnesses can cause an increase in metabolic activity as the body combats illness and disease in order to heal itself. Hypermetabolism is a common symptom of various pathologies. Some of the most prevalent diseases characterized by hypermetabolism are listed below.
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.
>30% increase in 18F-FDG SUL peak, with >0.8 SUL units increase in tumor SUV peak from the baseline scan in pattern typical of tumor and not of infection/treatment effect. or Visible increase in the extent of 18F-FDG tumor uptake. or New 18F-FDG avid lesions which are typical of cancer and not related to treatment effect or infection.
Fluciclovine is a [18 F]-tagged synthetic analog of the amino acid L-leucine.[11] [12] FACBC uptake by the tumor is related to functional activity of two amino acid transporters, [13] specifically sodium-dependent system ASC, with a lesser contribution by sodium-independent system L. [12] Although it is handled by the amino acid transporter system, it does not undergo terminally incorporative ...
Functional MRI and PET scan are the most common techniques that use haemodynamic response to map brain function. Physicians use these imaging techniques to examine the anatomy of the brain, to determine which specific parts of the brain are handling certain high order functions, to assess the effects of degenerative diseases, and even to plan ...
