Magnetic Resonance Imaging - MRI

Magnetic Resonance Imaging (MRI)

Magnetic resonance imaging is a diagnostic procedure that uses a combination of a large magnet, radiofrequencies and a computer to produce detailed images of organs and structures within the body.

The MRI machine is a large, cylindrical (tube-shaped) machine that creates a strong magnetic field around the patient. The magnetic field, along with a radiofrequency, alters the hydrogen atoms' natural alignment in the body. Computers are then used to form a two-dimensional (2D) image of a body structure or organ based on the activity of the hydrogen atoms. Cross-sectional views can be obtained to reveal further details. MRI does not use radiation, as do X-rays or computed tomography (CT scans).
