In a magnetic resonance imaging system and operating method for generating magnetic resonance image data of an object under examination, in order to acquire magnetic resonance raw data, an operating sequence is determined that has an excitation wherein an RF excitation pulse is radiated, and a readout procedure for receiving RF signals. In addition, a diffusion contrast gradient pulse sequence is generated that includes an uneven number of 2n+1 diffusion contrast gradient pulses switched in chronological succession, with the sum of the zero gradient moments of the diffusion contrast gradient pulses having the value zero and the sum of the first gradient moments of the diffusion contrast gradient pulses having the value zero. An RF refocusing pulse is switched between two of the diffusion contrast gradient pulses. |
