Abstract

Neuroimaging is the use of techniques to map the location of structural and functional regions within the living brain. It is used extensively in clinical practice to identify abnormalities, such as testing for brain tumors, stroke, and other neurological conditions. It is also increasingly used as a diagnostic tool on a finer scale for metabolic diseases and lesions, including differentiation of neurological disorders (e.g., Alzheimer's Disease versus frontotemporal dementia). Structural neuroimaging techniques generate anatomic images relating to the volume, position, and shape of a structure, whereas functional neuroimaging produces data relating to activities to the active processing of the brain, either in a “resting” state or a response to external stimulus. Functional imaging is also used to assess chemical composition and neuroreceptor characteristics. Structural neuroimaging is more likely to be used clinically, while functional neuroimaging is primarily associated with research endeavors.
