ABSTRACT:
Movements within volume elements or voxels of a body are depicted by subjecting this body to sequences of electro-magnetic excitation of the SSFP type during an NMR experiment. It is shown that by performing two series of excitation/reading sequences with different sensitization characteristics, it is possible to obtain images of molecular diffusion and/or perfusions in a far quicker and in a far more differentiated way than with standard types of excitation methods, of the spin-echo type for example.
