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.
