fMRI

abbreviation for

, Medicine/Medical.

1. functional magnetic resonance imaging: a procedure that uses MRI technology to measure and map brain activity by detecting changes in the brain’s blood flow and oxygenation. Also called functional MRI
2. functional magnetic resonance imager: a type of MRI scanner that is used in this procedure.

FMRI

abbreviation for

1. functional magnetic resonance imaging: a technique that directly measures the blood flow in the brain, thereby providing information on brain activity

FMRI

1. Abbreviation for f unctional m agnetic r esonance i maging. In FMRI, a patient is placed in a high magnetic field and delicate measurements of magnetic fields associated with processes like blood flow are made. In this way, the functioning of organs like the brain can be monitored as they occur. ( Compare MRI .)

Notes

FMRI images are used to determined which parts of the brain “light up” when a function such as speech or recognition is performed.

From Science Daily

These findings may also affect current approaches to interpreting fMRI scans, which measure changes in blood oxygenation within brain structures as they are activated.

From Science Daily

From Science Daily
