摘要:
In a method and magnetic resonance apparatus to generate magnetic resonance measurement data, k-space corresponding to the examination region is subdivided into a first region and a second region. The first region includes the k-space center, and a ratio of preparation pulses radiated by the radio-frequency antenna of the magnetic resonance apparatus to RF excitation pulses radiated by the radio-frequency antenna is greater in the first region than in a second region of k-space corresponding to the examination region that is not covered by the first region of k-space. Preparation pulses in the entirety of k-space corresponding to the examination region are therefore not radiated uniformly often, but instead a reduced number of preparation pulses is applied in the second region in comparison to the first region. The total measurement time to generate magnetic resonance data, as well as a SAR exposure, are reduced.
