Brain Mapping Technique (Technique (CAT (advantages (safer, more precise,…

- - - - safer
      - more precise
      - clearer image of brain structure
    - - doesn't indicate when the activity is occuring in the brain
  - - - can produce excellent images of bones & classify structures welll
      - Allow the shape, diameter, and lining of the GI
    - - can
  - - - no radiation remain in the patient's body after an x-ray examination
      - had no side effect in the typical diagnostic range
      - provide accurate picture of blood vessel in the brain
    - - injection of the contrast dye into the carotid artery or vertebral artery & carry to the brain arteries
    - - may produce allergic reaction in some patient
      - could dislodge vascular plaque & cause stroke
  - - - no x-ray / radioactive materials
      - resolution of the image is sharper & clearer
    - - slow for image to be generated
      - may cause claustrophobic reaction in some patient
  - - - able to trace rapid changes in neural activity
      - can record activations in brain
    - - may effect data validity
  - - - independent of behavioral respond
      - non-invasive
    - - functional significant
      - spontaneous or induce potential
  - - - provide an image of brain activity
    - - radioactive material used
