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

Notable studies

 * 1993, A comparison of brain MRI scans from 52 CFS patients and 52 controls found that 27% of CFS patients had findings considered abnormal, while only 2% of controls had findings considered abnormal. Abnormalities included T2 hyperintensities and ventricular enlargement.
 * 1999, A comparison of brain MRI scans from 39 CFS patients and 19 controls found that the 21 CFS patients who did not have a psychiatric diagnosis had significantly more T2 hyperintensities, compared to either controls or the 18 CFS patients with a psychiatric diagnosis.
