FUNCTIONAL SATURATION [2 records]

Record 1 2019-10-17

English

Subject field(s)
  • Magnetic Resonance Imaging
CONT

In the last decade, an exciting development has been functional MRI [magnetic resonance imaging](fMRI). The most commonly used method is the blood oxygen-level dependent(BOLD) technique... This method detects changes of blood levels of oxygen saturation(because of the concentration of deoxyhemoglobin), and an area with more oxygenated blood is more intense on T2-weighted images.

  • Imagerie par résonance magnétique
CONT

L'IRM [image par résonance magnétique] fonctionnelle (IRMf) est une imagerie indirecte de l'activité cérébrale basée sur la détection des variations du flux et d'oxygénation du sang secondaire à l'activation cérébrale. Elle est basée sur la technique BOLD.

OBS

BOLD est l'acronyme correspondant au terme anglais «blood oxygen-level dependent», qui signifie «dépendant de la concentration sanguine en oxygène».
