Abstract
In a method for the operation of a nuclear magnetic resonance tomography apparatus for separating water and fat signals a true FISP sequence is implemented with a repetition time TR, so that fat-bonded protons experience a phase rotation of approximately n·180° due to the effect of the chemical shift relative to water-bonded protons, with n being an odd number. Dependent on the further configuration of the sequence, either fat-bonded protons or water-bonded protons exhibit only a slight magnetization in the steady state condition, and thus contribute only little to the measured signal.
