In a method and for MR apparatus PPA imaging with radial data acquisition in magnetic resonance tomography, k-space is under-scanned by acquiring a number of projections phi with a coil array of M component coils, a shift operator C(±nDeltak) is determined for a projection phii on the basis of measured magnetizations along a projection phii±alpha0 that encompasses with phii an angle alpha0, with n=1, 2, . . . , M-1, the shift operator C(±nDeltak) is applied to individual points of projection phii in order to obtain calculated projection points, the determination and the application of the shift operator C(±nDeltak) are repeated for all projections phi, and an image is reconstructed in the spatial domain on the basis of the projections, which have been completed purely computationally.
