<P>PROBLEM TO BE SOLVED: To provide a method for improving three-dimensional slice-selective multi-slice excitation in MRI imaging and a system for performing the method. <P>SOLUTION: In a method for forming a magnetic resonance image, acquisition of data sets consisting of magnetic resonance signals of two spatial regions (OB) of a subject to be examined, wherein the spatial regions being displaced relative to one another along one spatial direction and overlapping in the respective edge region (27), is carried out by phase encoding, and for one of these spatial regions (OB), a modulation function (S) is determined that is limited to this entire spatial region (OB) and modulates the subject information, wherein foldover artifacts in the overlap regions (UB) of the different spatial regions (OB) are calculated on the basis of the modulation function and the MRI tomographic images of the non-edge regions (FOV, 28) of the respective spatial regions (OB) are combined without foldover artifacts in the spatial direction under consideration of the calculated foldover artifacts. <P>COPYRIGHT: (C)2008,JPO&INPIT
