How Does a Siemens PET Scanner Work?
PET stands for positron emission tomography. A positron is a negatively charged subatomic antiparticle, first discovered in 1932. Antiparticles mutually react with particles to create energy. A positron has the same mass as an electron, but is positively charged, whereas the electron is negatively charged. When a Siemens PET scanner is used, a compound labeled with a positron-emitting radionuclide is injected into the patient’s body. The activity of this substance throughout the body’s organs is measured by photomultiplier-scintillator detectors. As the radionuclide decays, positrons are annihilated by electrons, producing gamma rays detected by the photomultiplier-scintillators. After scanning the body, the Siemens PET scanner produces images of the organs using the data collected in this process.
What is a Siemens PET Scanner Used For?
The use of a Siemens PET scanner is widely applicable in the medical field. Images produced by PET scanners allow physicians to observe a great variety of body system functions and behaviors. Brain and heart functions in particular are one area PET scans are increasingly being used. The substance injected into the body is designed to accumulate in areas of abnormal activity, such as cancerous tumors and areas of inflammation, so these areas become apparent to doctors evaluating the images produced by a Siemens PET scanner.
Possible uses for a Siemens PET scanner are diverse. Below, read a description from Encyclopaedia Britannica of the many ways PET scanners are being used today.
PET has become a valuable tool in the detection of cancer and cancer metastasis (spread) and in the evaluation of heart conditions. PET studies have helped scientists understand more about how drugs affect the brain and what happens during learning, when using language, and in certain brain disorders, such as stroke, depression, and Parkinson disease. In addition, scientists are working to find ways to use PET to identify the biochemical nature of neurological disorders and mental disorders and to determine how well therapy is working in patients. PET has revealed marked changes in the depressed brain, and knowing the location of these changes helps researchers understand the causes of depression and monitor the effectiveness of specific treatments.Source: Encyclopaedia Britannica
