Record 1 - external organization data 2012-02-20

English

Subject field(s)
  • Chemistry
  • Compartment - Canadian Nuclear Safety Commission
DEF

A radioactive isotope of the element iridium that emits gamma radiation of energies from 0.3 MeV to 0.61 MeV [and that] has a half-life of 74.2 days ...

CONT

A wide range of radioactive contamination can be present because of the large number of radioisotopes produced, such as cobalt-60, carbon-14, molybdenum-99, thallium-201, gallium-67, iridium-192, xenon-133, iodine-131...

OBS

[It] is commonly used in gamma radiography.

OBS

In the symbols 192Ir and Ir192, the number (192) is a superscript.

Record 2 2011-05-30

English

Subject field(s)
  • Nervous System
CONT

The technique of RCBF involves the use of radioactive tracers, principally xenon-133, which are taken up in brain tissue and can be used to visualize which parts of the brain are most active.... The labeled xenon emits photons, which can be measured either by mapping flow on the surface of the brain or with a computer-assisted tomograph....

OBS

A highly experimental technique for dynamic brain imaging, which permits the actual observation of how the brain works when it performs certain tasks. It measures brain function rather than structure.

French

Domaine(s)
  • Système nerveux
CONT

Les techniques dynamiques [d'imagerie cérébrale], comme le flot sanguin régional (regional cerebral blood flow : RCBF) et la tomographie par émission de positons (PET-Scan), permettent une étude fonctionnelle. On sait ainsi que la région frontale est moins active dans la schizophrénie (hypofrontalité); par ailleurs, l'activité de la région temporale gauche augmente chez les patients hallucinés.

Key term(s)
  • débit sanguin local
