Magnetic resonance imaging

Magnetic Resonance Imaging (MRI) uses magnetic fields and radio waves to produce images of thin slices of tissues. MRI scans can be used to image many different parts of the body, including the brain, joints, major organs and even the whole body.

MRI scans can be used for many different purposes, e.g. to show:
 * abnormalities of the brain and spinal cord
 * abnormalities in various parts of the body such as breast, prostate, and liver
 * joint injuries or abnormalities, for example a knee injury
 * heart structure and function
 * areas of activity within the brain, using a functional MRI
 * blood flow through blood vessels and arteries
