Functional magnetic resonance imaging (fMRI) is an imaging scan that shows activity in specific areas of the brain. In medical settings, fMRI mainly helps plan brain surgeries and similar procedures.

Overview The fMRI concept builds on the earlier MRI scanning technology and the discovery of properties of oxygen-rich blood. MRI brain scans use a strong, uniform, static magnetic field to align …

Combining structural MRI, functional MRI and diffusion imaging may more broadly characterize normal and abnormal brain function, supporting biomarker studies of neurodegenerative or psychiatric …

Jul 21, 2025 · Functional Magnetic Resonance Imaging, or fMRI, is a specialized brain scan that measures and maps brain activity. It operates by detecting changes in blood flow associated with …

Functional MRI (fMRI) is used to evaluate subtle regional blood flow changes in the brain cortex that occur during patients performing specific tasks.

Instead of creating images of organs and tissues like MRI, an fMRI looks at blood flow in the brain to detect areas of activity. These changes in blood flow, which are captured on a computer and shown …

Current and accurate information for patients about functional MRI (fMRI) of the brain. Learn what you might experience, how to prepare for the exam, benefits, risks and much more.

Dec 19, 2025 · An fMRI is an imaging 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 …

An fMRI scan is a special type of MRI that shows how different parts of your brain are working. They help doctors measure blood flow in the brain without having to do surgery. fMRI imaging is a safe, …

Functional magnetic resonance imaging, or fMRI, allows Loyola Medicine doctors to measure blood flow within the brain and determine which parts of the brain are responsible for thoughts, speech, …
