Can fMRI predict when and if someone will regain consciousness after a traumatic brain injury?
What the fMRI machine detects is the shifting proportions of oxygenated blood in any given region of the brain.
Abbreviation for functional magnetic resonance imaging. 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.)
