Abstract
The invention provides a method and device for forming images by nuclear magnetic resonance in which an image is constructed by discrimination of the intrinsic parameters of the tissues examined. The image is formed by putting forward the degrees of attachment and mobility of the nuclei of the tissues. The parameters displayed represent the field heterogeneities at the microscopic and molecular levels. The method consists in acquiring a first image using conventional methods then, after slightly varying the orientater magnetic field, in acquiring another image using the same methods. Then an image of another type is formed by representing the relative variations of the relaxation times between this first and this second image.
