fMRI (Functional Magnetic Resonance Imaging)
fMRI or Functional Magnetic Resonance Imaging is a neuroimaging procedure using MRI technology that measures brain activity by detecting changes associated with blood flow. This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. When an area of the brain is in use, blood flow to that region also increases.
Pronunciation
fMRI: /ef-em-ar-eye/
Etymology
The term "fMRI" is an acronym derived from "Functional Magnetic Resonance Imaging". The term "functional" is used to denote that this imaging technique is used to understand the functional areas of the brain, while "Magnetic Resonance Imaging" refers to the use of magnetic fields and radio waves to create detailed images of the body.
