WebWhat is an MRI machine and how does it work? Hit play to find out! WebA functional magnetic resonance imaging (fMRI) scanner uses a powerful magnetic field to detect brain activity. When an area of the brain becomes more active, such as when you wave your hand, there is an increase in blood flow to that region. An fMRI imaging scan takes advantage of activated neurons requiring more oxygen from red blood cells.
