Abstract

Abstract Translated from French On représente les mouvements à l'intérieur des éléments de volume, ou voxels, d'un corps, en soumettant ce corps à des séquences d'excitation électromagnétique (TR) de type SSFP au cours d'une expérimentation RMN. On montre qu'en effectuant deux séries de séquences d'excitation-lecture avec des caractéristiques (24) de sensibilisation différentes, on peut obtenir des images de diffusion moléculaire et/ou de perfusion bien plus rapidement et bien mieux différenciées qu'avec des procédés d'excitation de type classique, de type à écho de spin par exemple. We represent the movements inside the volume elements, or voxels, of a body, by subjecting this body to electromagnetic excitation (TR) sequences of the SSFP type during an NMR experiment. It is shown that by performing two series of excitation-reading sequences with different sensitization characteristics (24), it is possible to obtain molecular diffusion and / or perfusion images much faster and much better differentiated than with methods. excitation of the classical type, of the spin echo type for example.
