摘要：
A method of magnetic resonance imaging is provided. The method includes the steps of applying a preparation pulse sequence to a subject (16) disposed in an examination region (14), acquiring k-space data related to a plurality of k-space trajectories through the center of k-space such as radial trajectories and reconstructing a first image form the k-space data wherein data within a region (210) around the center of k-space (205) of at least a first of the k-space trajectories is not used. Rather, data of only a limited number of views within said region is used for image reconstruction. Hence, image contrast is essentially determined by said limited number of views.
