ABSTRACT:
In a method and MRI apparatus for the minimization of streak artifacts in modular k-space scanning in magnetic resonance imaging, an odd integer k-space scanning module number Nφ=2n+1 is defined that defines the number of incrementally rotated repeated modules of the k-space scanning process, a slice selection gradient selects any slice in the range of the object to be examined, and data for all Nφangle-oriented k-space scanning modules in the selected slice acquired such that each k-space scanning module has an azmuthal distance ofΔφ2=360°2Nφfrom both adjacent projections, with the direction of the scanning of the adjacent k-space scanning modules alternating.
