Which non-invasive diagnostic tool uses magnetic fields and radio waves to create images of the inside of the body?

Fact

Did you know?

Magnetic resonance imaging uses an intense magnetic field, radio waves and field gradients to produce detailed images of tissue. It does not use X-rays and makes it possible to examine the brain, joints, muscles and many organs. Its development results from numerous stages: nuclear magnetic resonance was discovered in the 20th century, then Paul Lauterbur showed how to form images using gradients, and Peter Mansfield improved the methods of reconstruction and speed. Raymond Damadian also conducted early research on differences between tissues. Attributing the MRI to a single person therefore does not reflect this collective story.
