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. Emission computed tomography - Wikipedia

   en.wikipedia.org/wiki/Emission_computed_tomography

   Types include positron emission tomography (PET) and Single-photon emission computed tomography (SPECT). SPECT is commonly used to diagnose certain diseases. [ 1 ] SPECT imaging is conducting by injecting a radioactive probe (or tracer) into the person's blood stream. [ 1 ]

5. 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 ...

6. Nuclear medicine - Wikipedia

   en.wikipedia.org/wiki/Nuclear_medicine

   In addition, there are nuclear medicine studies that allow imaging of the whole body based on certain cellular receptors or functions. Examples are whole body PET scans or PET/CT scans, gallium scans, indium white blood cell scans, MIBG and octreotide scans. Iodine-123 whole body scan for thyroid cancer evaluation.

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 .
