MRI What is MRI? Magnetic resonance imaging (MRI) is a noninvasive method of using a magnetic field and radio waves to produce detailed images of the inside of the human body. Doctors use MRI to help diagnose medical conditions and disorders. MRI is instrumental to detecting: • central nervous system disorders • brain and organ tumors • brain abnormalities corresponding with dementia • eye abnormalities • reproductive system problems • bladder problems • blood vessel plaques and blockages • bone and joint damage or infection • breast cancer • risk of stroke MRI Safety While no known effectives are associated with MRI, the magnetic field of the scanner does attract metal objects and electronics, particularly those containing iron. Patients are advised to remove all accessories or objects that may contain metal from their bodies. The physician or technologist should also be informed of any metallic implants and devices the patient may have, from artificial heart valves to prostheses to dentures, and others. Patients with pacemakers should not receive MRI scans. The effects of MRI imaging on fetuses are unknown. Pregnant women should consult their physicians on whether to postpone the exam or opt for alternative procedures. A History of MRI Developed by Dr. Raymond Damadian and a team of graduate students at SUNY Downtown Medical Center, the first ever MRI exam was performed on July 3, 1977. While Dr. Damadian's methods were used primarily for the study of chemical structures, MRI continues to develop an increasingly vital role in the medical field. In 2003, Paul Lauterbur and Sir Peter Mansfield were awarded the Nobel Peace Prize in Medicine for discovering how to use MRI to produce two-dimensional images of the body.
