Saturation-prepared recording of MR image data

A method for a saturation-prepared recording of magnetic resonance (MR) image data, the method comprising:

• establishing at least two measurement slices in an examination volume of an examination object, wherein the examination volume has adjacent slices which each adjoin at least one measurement slice of the at least two measurement slices;
