A T1* versus SS scatter plot (left) and corresponding image (right) showing the fuzzy clustering results with infarct core (green), gray zone (yellow), myocardium (blue) and blood (red). Inversion-recovery SSFP yields multiple delayed enhancement images at different inversion times that have been used to create pixel-by-pixel parameter maps. Fuzzy clustering methods were developed to use the paramter maps to detect areas of heterogeneous infarct.
