For generating of magnetic resonance exposures of an examination subject, a dielectric element with high dielectric constant is positioned on the examination subject to locally influence the B.sub.1 field distribution, the dielectric element being formed primarily of material whose magnetic resonance line(s) is/are shifted by at least a specific degree relative to the magnetic resonance line of water protons for a given magnetic field. In a measurement for generation of a magnetic resonance exposure a measurement sequence is used, such in the acquisition of the raw image data the dielectric material of the dielectric element supplies no signal contributions for the image generation and/or the signals caused by the dielectric material of the dielectric element can be separated from the signals caused by the examination subject.
