Adaptive sampling of k-space allows the reconstruction of images with various spatial and temporal resolutions from the same data set and is therefore suitable for dynamic MRI. 3D projection reconstruction based on multidimensional golden means (golden 3D-PR) achieve this flexibility for any time interval. In this work, partial fat saturation in combination with the k-space-weighted image contrast (KWIC) technique is used for fast fat suppression of golden 3D-PR. KWIC processing greatly increases the efficiency of the applied partial fat saturation. The new technique allows fat suppression of adaptive golden 3D-PR data sets with high temporal resolution.
