2. Positron emission tomography - Wikipedia

   en.wikipedia.org/wiki/Positron_emission_tomography

   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 ...

3. PET-CT - Wikipedia

   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.

4. Brain positron emission tomography - Wikipedia

   en.wikipedia.org/wiki/Brain_positron_emission...

   PET scanning is also used for diagnosis of brain disease, most notably because brain tumors, strokes, and neurondegenerative diseases (such as Alzheimer's disease and Parkinson's disease) all cause great changes in brain metabolism, which in turn causes detectable changes in PET scans. PET is probably most useful in early cases of certain ...

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.

6. Emission computed tomography - Wikipedia

   en.wikipedia.org/wiki/Emission_computed_tomography

   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 ...

7. PSMA scan - Wikipedia

   en.wikipedia.org/wiki/PSMA_scan

   A PSMA scan is a nuclear medicine imaging technique used in the diagnosis and staging of prostate cancer. It is carried out by injection of a radiopharmaceutical with a positron or gamma emitting radionuclide and a prostate-specific membrane antigen (PSMA) targeting ligand .
