A novel chemical species separation method is presented. We repetitively switch a saturation pulse and acquire multiple images afterwards to get a global behavior, a paradigm, of the data. The correlation and significance of each pixel with the paradigm is calculated and used for visualization of the saturated species. The results are compared with conventional iterative decomposition of water and fat with echo asymmetry and least squares estimation (IDEAL), giving good agreement.
