1.1 MRI modalities

The phenomenon of nuclear magnetic resonance (NMR) was first demonstrated by Rabi in 1938. A few years later, Purcell and Bloch defined the basis of NMR detection mechanisms. These discoveries, for which their authors were awarded the Nobel Prizes in Physics in 1944 and 1952, led to the development of magnetic resonance imaging (MRI).

This imaging, which gives access to the observation of internal structures, began to be applied to the medical field in the early 1970s
