WebOct 1, 2024 · An fMRI is a test that uses strong magnetic fields to create pictures of the inside of your brain. It’s used to look at brain activity by measuring the amount of blood flowing to different parts of your brain. 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.
