functional magnetic resonance imaging


Also found in: Dictionary, Thesaurus, Acronyms, Encyclopedia, Wikipedia.

functional magnetic resonance imaging

brain activity revealed by manipulating the MR signal to show regional oxygen uptake.

functional magnetic resonance imaging

n. Abbr. fMRI
Magnetic resonance imaging that provides three-dimensional images of the brain showing areas of increased blood flow that correlate with specific brain functions.

functional magnetic resonance imaging (fMRI)

a radiographic technique for imaging brain activity. In fMRI the examiner takes a rapid succession of scans designed to detect increases in oxygen consumption in various regions of the brain, which reflects small changes in blood flow and increased activity in certain cells.

(fMRI) (fŭngkshŭn-ăl mag-netik rezŏ-năns imăj-ing)
Brain activity revealed by manipulating the MR signal to show regional oxygen uptake.

functional magnetic resonance imaging (fMRI),

n a diagnostic tool that uses Magnetic Resonance Imaging (MRI) equipment to study ongoing brain activity. Provides a real time depiction of brain functioning by tracking blood flow in the brain, an indicator of brain activity. Used to study mental illnesses.
