  1. Brain Scanning Technology

  2. Today’s Objective • The diverse methods used to scan the bran: practical use that can aid doctors to determine psychological & medical issues.

  3. 1. Computed Tomography Scan (CT) • Uses X rays to get detailed pictures of body parts and the brain.

  4. Used for finding abnormalities in parts of your body and brain. EX.- Tumors, cysts, enlarged parts, cancers, foreign objects, internal bleeding. Help guide needles during biopsies. Like slices of bed. Images can be combined to create 3D images

  5. 2. Magnetic Resonance Imaging (MRI) • Uses a large magnet, combined with radio waves to take pictures of the head. • Show tissue damage, inflammation, tumors, blood flow.

  6. Show tissue damage, inflammation, tumors, blood flow/ clots, abnormalities. Plaques on a brain with MS

  7. 3. Positron Emission Tomography (PET) • Measures brain activity by injecting the person with positively charged particles (glucose) and seeing which parts of the brain are activated. http://www.youtube.com/watch?v=_myFX7-4pJw&feature=fvsr

  8. Used to check for decreased or increased brain activity which can indicate diseases such as Alzheimer’s, MS, Parkinson’s, stroke, schizophrenia & cancers.

  9. 4. Electroencephalograph (EEG) • Metal electrodes are placed all over your head to measure its brainwaves.

  10. Helps diagnose head injuries, infections, sleep disorders, investigate unconsciousness, and monitor the brain during surgery

  11. Seizure
