An MR tomography method for generating water and fat images and an apparatus for performing the method. In one embodiment each sequence, consisting of a high-frequency pulse and different gradient fields, is executed twice, the gradient fields being influenced so that the distance between the high-frequency pulse and the echo signal in one execution of a sequence deviates from that in the other execution of the sequence by a given amount. Water images and fat images can thus be formed by summing and subtraction, respectively. In a second embodiment, two read phases are provided in each sequence.
