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 …

Dec 13, 2021 · Invented in the early 1990s, functional magnetic resonance imaging (fMRI) is a type of noninvasive brain imaging technology that detects brain activity by measuring changes in blood flow.

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 …

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.

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

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

Nov 17, 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 …
