摘要： In a magnetic resonance method and apparatus for imaging a particle that is located in an examination subject, a pulse sequence is emitted that includes an excitation pulse that generates a transverse magnetization of the examination subject from a magnetization appearing in a basic magnetic field, so the particle causes a magnetic interference field in the applied basic magnetic field in a magnetic resonance measurement. After the excitation pulse, at least one spectrally selective refocusing pulse is generated in a non-resonant frequency range at the generation of a spin echo.
