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 …

Jun 24, 2025 · Learn the differences between fMRI and MRI scans, how they work, their uses, and what to expect during the imaging test.

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.

The fMRI data is analyzed to identify brain areas in which the MR signal has a matching pattern of changes, and these areas are taken to be activated by the stimulus (in this example, the visual …

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 …

Functional magnetic resonance imaging (fMRI) uses MR imaging to measure the tiny changes in blood flow that take place when a certain part of your brain is working.

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 …

Nov 29, 2025 · Functional magnetic resonance imaging (fMRI), neuroimaging technique used in biomedical research and in diagnosis that detects changes in blood flow in the brain.
