Abstract
In a method and magnetic resonance (MR) apparatus for avoiding artifacts in scan data recorded by execution of a spin-echo sequence, an excitation pulse is radiated, at least one refocusing pulse is radiated, and at least one echo signal is read out. Following the radiation of the excitation pulse and before the readout of the at least one echo signal, at least two artifact-avoidance gradients with different amplitudes are activated, wherein the moments of the artifact-avoidance gradients balance each other.
