ABSTRACT:
A magnetic resonance imaging method for generating separate fat and water images of at least one slice utilizes a plurality of sequences acting on the slice in the presence of a steady magnetic field, each sequence including at least one first RF pulse, followed by a phase encoding gradient during which the spin resonance signal formed in the slice is detected, groups of sequences being formed with a position in time of the measuring gradient and/or a further RF pulse, if any, which differs from one group to another, the number of sequences per slice being twice as large as necessary for the formation of a similar image without fat/water separation. The phase encoding gradient is varied in steps from one sequence to another. The separate fat and water images (F,W) are formed from the resultant spin resonance signals by 2D Fourier transformation.
