Magnetic Resonance Imaging

Claimed by Noah Schaich

Magnetic Resonance Imaging (MRI) is a medical device that uses radio waves and strong magnets connected to a computer to create a cross-sectional view of organs and tissue within the human body.

History

The concept for an MRI machine comes from nuclear magnetic resonance(NMR), which is when atomic nuclei absorb or emit radio waves in the presence of a strong magnetic field. This concept was expanded on by Raymond Damadian, who discovered that if using this technique to look at cells in the human body, cancerous cells would appear different because they contain more water, and thus more hydrogen atoms. The first NMR image was produced in 1973 by Paul Lauterbur, and 4 years later, in 1977, the first body scan using an MRI prototype machine was produced.
