Neuroimaging is a method by which parts of the nervous system (central and peripheral) are observed with regards to their structure and activity. There are two categories of neuroimaging techniques:

  1. Functional: a type of neuroimaging technique that measures blood flow in a part of the nervous system.
  2. Structural: a type of neuroimaging technique that takes still photos of parts of the nervous system to assess changes/damage.

The specific Functional neuroimaging techniques are: fMRI, PET, and SPECT.

The specific Structural neuroimaging techniques are: CT and MRI.
