The term “neuroimaging” includes the use of various technologies to either directly or indirectly image the structure or function of the brain and its response to normal and abnormal processes. Structural neuroimaging attempts to noninvasively visualize gross pathology in the brain and can be used for the diagnosis of gross (large-scale) intracranial diseases, such as tumors. The most common structural imaging techniques are X-ray, computed tomography (CT), and magnetic resonance imaging (MRI). Functional neuroimaging techniques are primarily based on regional cerebral blood flow, regional cerebral metabolic rate of glucose consumption, or neuroreceptor signaling. They are most commonly used to quantify neuroreceptor status, diagnose diseases that cause metabolic derangement, and study the neurobiology and cognitive psychology associated with various neurological and neuropsychiatric disorders, such as major depression. The most common functional neuroimaging techniques are positron emission tomography (PET), single-photon emission tomography (SPECT), and functional magnetic resonance imaging (fMRI).
