1. The response of polar atoms to discrete radiation frequencies under the influence of strong magnetic fields.
2. Ed Purcell and Felix Bloch got the nobel prize in 1952 for NMR.
3. First human images were taken in 1978.
4. Earths magnetic field = .5 Gauss
5. MRI has great low contrast imaging and has no ionizing radiation.
6. Free Induction Decay = one radiowave turned is turned off and the left over energy stored in the protons is recycled to form another radiowave.
