Magnetic resonance imaging (MRI) is an imaging technique used to visualize the structure and parts of body and their function. It produces detailed images of the body using a powerful magnetic field, radio waves and a computer. 2D and 3D images can be acquired with the technique, with or without the use a contrast material to highlight the body parts. The radio waves sent and received in the strong magnetic field produce signals which are processed by a computer to generate a series of virtual ‘slices’ (two-dimensional cross-sectional images) of the body.

MRI does not use ionizing radiation (x-rays) and is generally a safe, non-invasive and painless procedure with almost no risks. Implanted metal or electronic medical devices may malfunction during an MRI exam. This imaging technique is widely used in diagnosing diseases, staging them and to monitor their progress. It helps evaluate abnormalities of the brain, neck, spine, joints, blood vessels, organs of the chest and abdomen like heart, liver, kidneys, etc.
