What is an MRI (Magnetic Resonance Imaging)? - Live Science

Web6 apr. 2016 · During functional MRI, or fMRI, the scanner is specifically sensitive to oxygenated blood. Since active parts of the brain use up a lot of oxygen, new oxygen must be delivered through the blood stream. As a result, fMRI infers brain activity by tracking where oxygenated blood is increasing in the brain (see the image in Figure 1D). WebAn fMRI scan uses the same technology as an MRI scan. An MRI is a noninvasive test that uses a strong magnetic field and radio waves to create an image of the brain. The image an MRI scan produces is just of …
