WebOverview. Magnetic resonance imaging (MRI) is a type of scan that uses strong magnetic fields and radio waves to produce detailed images of the inside of the body. An MRI scanner is a large tube that contains powerful magnets. You lie inside the tube during the scan. An MRI scan can be used to examine almost any part of the body, including the: WebfMRI is used to evaluate subtle regional blood flow changes in brain cortex that occur during patient performance of specific tasks while inside the bore of a high-field MRI scanner (generally, at a field strength of 3 Tesla).
