WebFunctional MRI (fMRI) Functional magnetic resonance imaging (fMRI) measures the small changes in blood flow that occur with brain activity. It may be used to examine which parts of the brain are handling critical functions, evaluate the effects of stroke or other disease, or to guide brain treatment. fMRI may detect abnormalities within the brain that cannot be … WebNov 10, 2024 · A: When additional energy in the form of a radio wave is added to the applied magnetic field, the magnetic vector is deflected. The radio frequency (RF) wave that causes the hydrogen nuclei to resonate is dependent on the target element (here, hydrogen) and the strength of the magnetic field. To make the MRI work, the strength of the magnetic ...
