What types of brain scans, or neuroimaging tests, are there?
A. There are two main types of neuroimaging tests: structural and functional. • Structural imaging creates a “snapshot” of the brain’s structure, including bone, tissue, blood vessels, tumors, infection, damage, or bleeding such as from a stroke. • Functional imaging reveals the brain’s ever-changing activity and chemistry by measuring the rate of blood flow, chemical activity, and electrical impulses in the brain during specific tasks.
