A noninvasive, diagnostic scanning procedure that produces detailed, computerized images. The use of a "contrast agent" or dye enhances the detail of the images. Sequencing of these images may help physicians visualize the body's functioning, thus aiding differential diagnosis.
An imaging technique used to examine changes in the activity of the working human brain. go to glossary index
a form of magnetic resonance imaging of the brain that registers blood flow to functioning areas of the brain
A new form of Magnetic resonance imaging (MRI) that allows brain function to be studied. For more information: BipolarWeb FMRI reference.
An imaging technique based on echo-planar imaging which is used to determine brain function. [ Chapter 12
The use of magnetic resonance imaging (MRI) to learn which regions of the brain are active in a specific function, as in speech. Abbreviated fMRI. See also: Magnetic resonance imaging
Modification of magnetic resonance imaging (MRI) which allows researchers to take pictures of the brain so quickly that metabolic changes can be measured, resulting in a picture of the brain at work rather than its structure alone.
A type of imaging that measures increases in blood flow within the brain.
A noninvasive tool used to observe functioning in the brain or other organs by detecting changes in chemical composition, blood flow, or both.
Functional magnetic resonance imaging (fMRI) is the use of MRI to measure the hemodynamic response related to neural activity in the brain or spinal cord of humans or other animals. It is one of the most recently developed forms of neuroimaging.
