positron A subatomic particle of mass and charge equal to the electron but of opposite (i.e., positive) charge.
Synonym: positive electron.
(05 Mar 2000)
positron emission tomography <radiology> A highly specialised research imaging technique using short lived radioactive substances - usually those made with a cyclotron. This technique is very sensitive in picking up active tumour tissue but does not measure the size of it.
Tomographic images are formed by computer analysis of photons detected from annihilation of positrons emitted by radionuclides incorporated into biochemical substances; the images, often quantitated with a colour scale, show the uptake and distribution of the substances in the tissue, permitting analysis and localization of metabolic and physiological function.
Because the half-lives of the radionuclides are so short (20 minutes to 2 hours), and the equipment expensive, PET is rarely used in a clinical setting. But since its development in the mid-1970s, it has proved the most important tool yet devised for experimental investigation of the living brain, whether healthy, traumatised, or diseased. With CT and MRI, it represents a new generation of computer imaging techniques that have revolutionised medicine and physiology.

  • Positron-Emission Tomography - »õâ An imaging technique using compounds labelled with short-lived positron-emitting radionuclides (such as carbon-11, nitrogen-13, oxygen-15 and fluorine-18) to measure cell metabolism. It has been useful in study of soft tissues such as CANCER; CARDIOVASCULAR SYSTEM; and BRAIN. SPECT is closely related to PET, but uses isotopes with longer half-lives and resolution is lower.

positron (Or antielectron.) A positively charged subatomic particle with the same mass and charge magnitude as that of the electron. The electron's antiparticle, the positron was first observed in 1932 in cosmic rays by Carl Anderson using a Wilson cloud chamber. Boorse, HA, and L. Motz, 1966: The World of the Atom, Vol. II, 1261?267. Anderson, CD, 1961: Amer. J. Phys., 29, 825?30.

positron emission tomography An imaging technique used for measuring blood flow and metabolism within body tissues, including the heart and brain.

positron emission A nuclear reaction in which a positron is emitted. Positron emission leads to a decrease by one in the atomic number and no change in the mass number of the nuclide.
