- Magnetic resonance imaging (mri) is a noninvasive medical test that physicians use to diagnose medical conditions mri uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed pictures of organs, soft tissues, bone and virtually all other internal body structures mri does not use ionizing radiation (x-rays).
- Mri, as with all medical imaging techniques, is a relatively new technology with its foundations beginning during the year of 1946 felix bloch and edward purcell independently discovered the magnetic resonance phenomena during this year, and were later awarded the nobel prize in 1952.
