Abstract: In a method and apparatus for the correction of artifacts in magnetic resonance images (MR) acquired with an MR pulse sequence in which gradients are switched simultaneously during the radiation of at least one non-selective excitation pulse, measurement data acquired with the pulse sequence in k-space are loaded into a processor, in which a perturbation matrix is determined on the basis of spatial and k-space point data of the acquired measurement data and the gradients used during the excitation.

The corrected image is then stored or displayed.

Abstract: In a magnetic resonance (MR) method and system to generate a series of MR images to monitor the position of an interventional device located in an examination region, radial scanning of k-space is combined with other scans, in particular for the k-space center. The measurement time until the entirety of k-space corresponding to the imaging region is scanned is thereby markedly shortened in total. The short echo times that are possible with this reduce susceptibility artifacts in the reconstructed image data and enable a depiction of tissue or substances with very short T2 values, for example plastics. Due to the rapidly repeated excitation and acquisition of measurement data and the reconstruction of image data, it is possible to monitor a position of the intervention device in the examination region.

During the excitation duration, a time-resolved reception signal is detected. The projection data record is determined from the reception signal through evaluation.
