FMRI

abbreviation for
(Pathology) functional magnetic resonance imaging: a technique that directly measures the blood flow in the brain, thereby providing information on brain activity
ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.fMRI - a form of magnetic resonance imaging of the brain that registers blood flow to functioning areas of the brain
magnetic resonance imaging, MRI - the use of nuclear magnetic resonance of protons to produce proton density images
BOLD FMRI - functional magnetic resonance imaging that relies on intrinsic changes in hemoglobin oxygenation

The basis of fMRI is that deoxygenated blood is magnetic whereas oxygenated blood is not.
We wanted a procedure that would allow us to effectively measure pain processing in MS without it being uncomfortable for participants, which is important if fMRI pain imaging is to become part of the normal protocol along with MRI," Dr.
Part of the work will build on a technique used by researchers at Cambridge and Liege universities where fMRI was used on a 23-year-old woman in a persistent vegetative state following a severe road accident.
These methods measure dynamic brain changes that have a time course similar to brain sensory, motor or cognitive activities, and include methods such as electroencephalography (EEG), positron emission tomography (PET), fMRI, and near-infrared spectroscopy (NIRS).
When a functional MRI (fMRI) study of the brain is performed, about 30 to 60 images covering the entire 3-D brain are repeated hundreds of times like the frames of a movie but, with fMRI, like a 3-D movie," Feinberg said.
