NMR and MRI in retrospect

Abstract
The success in clinical practice of magnetic resonance imaging (MRI) is a result of the symbiosis of the science of NMR with the computer and the availability of appropriate magnetic fields. A brief survey with some history is presented of NMR phenomena which are basic to the interpretation of MRI signals. Special exotic effects or procedures, such as stochastic NMR and line narrowing techniques of high-resolution NMR spectroscopy have a potential to play a role in future MRI systems.
