WebFunctional MRI (fMRI) evaluates blood flow in the brain called the blood oxygenation level dependent (BOLD) contrast technique. This means that brain activity can be picked up by the MRI scanner because of tiny chemical changes in the blood. WebfMRI is a non-invasive diagnostic test that provides an indirect measure of blood flow to nerve cells. When an area of the brain is in use, blood flow to that region also increases, when a brain area is less active blood flow decreases. Functional MRI was developed in the 1990s and has been used as a valuable research tool.
