Claim Text:
1. A method for acquiring magnetic resonance (MR) measurement data from an examination subject, comprising: operating an MR data acquisition unit according to an MR data acquisition sequence to acquire MR measurement data from an examination region of an examination subject in the MR data acquisition unit; in said MR data acquisition sequence, acquiring said MR measurement data in a plurality of individual MR data acquisitions by radiating a plurality of excitation pulses; also in said MR data acquisition sequence, radiating a pre-pulse before a predetermined number of said individual MR data acquisitions that produces a magnetization of nuclear spins of at least two materials in said imaging region, said magnetization being a source of contrast between said at least two materials in an image of the imaging region to be reconstructed from said MR measurement data; entering said MR measurement data into an electronic memory organized as k-space corresponding to said imaging region, by entering MR measurement data into a first region of k-space, which does not include a center of k-space, radially along spokes emanating from the center of k-space, and entering MR measurement data into a second central region of k-space, which remains without said first region, in a Cartesian manner; entering MR measurement data into at least one portion of said second region of k-space that is situated nearest the center of k-space, as central measurement points after a first radiation of said pre-pulse following a zero crossing of the magnetization of one of said at least two materials; and making k-space filled with said MR measurement data available from said memory in electronic form as a data file.
