Claim Text:
1. A method to generate magnetic resonance (MR) data of an examination region of an examination subject, comprising: operating an MR data acquisition unit having a measurement volume in which the examination region of the examination subject is located, to generate echo signals originating from said examination region by radiating a plurality of radio-frequency (RF) excitation pulses successively with an RF antenna of said MR data acquisition unit, and generating respectively different magnetic field gradients with a gradient coil system of said MR data acquisition unit to spatially encode said echo signals until data entries corresponding to said examination region have been entered into k-space in a memory, and radiating preparation pulses into the examination region of the examination subject with said RF antenna with a ratio of said preparation pulses to said RF excitation pulses being larger in a first region of k-space corresponding to said examination region and that comprises at least a center of k-space, than a second region of k-space corresponding to said examination region, said second region not being covered by said first region and wherein said first region is a region surrounding said k-space center with a radius depending on a time t acquiring said echo signals with an RF reception antenna after each radiated RF excitation pulse; and making said entries in k-space available from said memory as a measurement data file.
