- understand the function each area in the brain serves
- locate areas that are affected by brain injuries
Computed Tomography Scan (CT Scan)
-uses x-ray beams to pass through the head.
-shows structure of the brain, but not function.
Position Emission Tomography (PET)
-detects radioactive material that is injected or inhaled to produce an image of the brain
-radioactive material moves to area of the brain that is in use
-allows you to see function
Magnetic Resonance Imaging (MRI)
-detects radio frequency signals produced by displacing radio waves in a magnetic field
-shows structures of brain
Functional Magnetic Resonance Imaging (fMRI)
-detects changes in blood flow to the brain
-shows structure and function of the parts of the brain
