FIGURE 6. Histogram of DRA severity scores for each slice (total of 30 slices for the n=10 studies) for the conventional FPP imaging method (light gray) and the proposed method (dark gray).
The mean DRA score (averaged across n=10 studies) is lower for the proposed method (1.2 vs. 2.0 for the conventional and proposed methods, respectively; p<0.01). Most notably, the number of myocardial slices with severe DRA (artifact score = 3 or 4) is significantly lower for the proposed method compared to the conventional method (10 slices vs. 1 slice for the conventional and proposed methods, respectively).
