Magnetic resonance imaging Magnetic resonance imaging is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body in both health and disease. MRI scanners use strong magnetic fields, electric field gradients, and radio waves to generate images of the organs in the body. MRI does not involve X-rays and the use of ionizing radiation, which distinguishes it from CT or CAT scans. Magnetic resonance imaging is a medical application of nuclear magnetic resonance.

Magnetic resonance imaging (MRI) is a test that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body.In many cases, MRI gives different information about structures in the body than can be seen with an X-ray, ultrasound, or computed tomography (CT) scan.agnetic resonance imaging (MRI) is done for many reasons. It is used to find problems such as tumors, bleeding, injury, blood vessel diseases, or infection. MRI also may be done to provide more information about a problem seen on an X-ray, ultrasound scan, or CT scan.

MRI (High-Field, Non-Claustrophobic) MRI (High-Field, Non-Claustrophobic) What is Magnetic Resonance Imaging (MRI)? Magnetic resonance imaging (MRI) is a technique that allows doctors to see inside the body in remarkable detail without using radiation. Instead, MRI uses a powerful magnet, radio waves, and a sophisticated computer system to produce pictures of various parts of the body. All Metro Imaging facilities feature high-field, non-claustrophobic MRI units.

Magnetic Resonance Imaging (MRI) Overview. Magnetic resonance imaging (MRI) is the diagnostic tool that currently offers the most sensitive non-invasive way of imaging the brain, spinal cord, or other areas of the body.It is the preferred imaging method to help establish a diagnosis of MS and to monitor the course of the disease.RI uses a powerful magnetic field that: 1  Makes the hydrogen protons in water molecules line up in the direction of the magnetic field. 2  Once the hydrogen protons have been lined up, radio waves are used to knock them out of line. 3  When the radio waves are stopped, the protons relax back into line.

Physiological Psych 2200 Functional magnetic resonance imaging or functional MRI (fMRI) is a functional neuroimaging procedure using MRI technology that measures brain activity by detecting changes associated with blood flow.This technique relies on the fact that cerebral blood flow and neuronal activation are coupled.ince the early 1990s, fMRI has come to dominate brain mapping research because it does not require people to undergo shots, surgery, or to ingest substances, or be exposed to radiation, etc. Other methods of obtaining contrast are arterial spin labeling and diffusion MRI.

- The purpose of structural imaging is to visualize the various structures of the brain and any physical abnormalities that may affect them (such as tumours, bleeding, blood clots, or birth deformities). The purpose of functional imaging is to measure activity in certain parts of the brain while it performs certain tasks. Functional imaging is used chiefly in fundamental research, to improve our understanding of the various structures of the human brain. But functional imaging is also used to diagnose the foci of epileptic seizures, as well as to identify, prior to brain surgery, parts of the brain that perform essential functions and must be kept intact no matter what.

Functional magnetic resonance imaging This is a type of specialized brain and body scan used to map neural activity in the brain or spinal cord of humans or other animals by imaging the change in blood flow (hemodynamic response) related to energy use by brain cells.euroimaging methods such as fMRI offer a measure of the activation of certain brain areas in response to cognitive tasks engaged in during the scanning process. Data obtained during this time allow cognitive neuroscientists to gain information regarding the role of particular brain regions in cognitive function.
