WebMagnetic resonance imaging (MRI) is an imaging technique used in medical physics that produces two- and three-dimensional images of the interior of the human body. MRI is based on the nuclear magnetic resonance (NMR) effect, which explains the interaction between an external magnetic field and the nuclei of certain atoms, mainly hydrogen. … Functional magnetic resonance imaging or functional MRI (fMRI) 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.
