Contrast prepared MRI involving non-cartesian trajectories with oversampling of the center of k-space

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...

More Information
Summary: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.
