Claim:
1. A magnetic resonance (MR) apparatus comprising: an MR data acquisition unit; a computer configured to operate the MR data acquisition unit according to an MR data acquisition sequence in which raw MR data acquired from an imaging area of an examination subject are entered into an electronic memory organized as k-space, by entering said raw MR data into a first region of k-space, which does not include a center of k-space, radially along a number of straight spokes emanating from the center of k-space, and wherein at least two phase coding gradients are completely ramped up before exciting nuclear spins in the examination subject, and by entering said raw MR data into a second, central region of k-space, that remains without the first region, in a Cartesian manner and wherein a contrast-increasing pre-pulse is radiated before a predetermined number of individual acquisitions of said raw MR data; said computer being configured to automatically set a number of said spokes to cause a data entry point, defined in a Cartesian manner, nearest to the center of k-space to be filled with said raw MR data at a predetermined point in time that is optimized with regard to at least one of signal-to-noise ratio and said contrast in an MR image reconstructed from said raw MR data; and said computer being configured to make k-space, with said raw MR data entered therein according to the set number of spokes, available as a data file at an output of said computer in a format for further processing into image data.
