ABSTRACT:
The invention relates to a method of generating separate fat images and water images and to an apparatus for performing this method. Separate fat images and water images are obtained by means of a sequence consisting of three high-frequency pulses, the second and the third high-frequency pulse having an identical flip angle and being situated at a distance in time from one another which corresponds to half the reciprocal value of the difference between the Larmor frequencies of water-bound hydrogen protons on the one hand and fat-bound hydrogen protons on the other hand, or to an odd multiple thereof.
