Web3 Feb 2014 · Perfusion in each segment was graded on a four-point scale (transmural ischaemia index: 0 = normal, 1 = inconclusive, 2 = subendocardial defect, 3 = transmural defect). A typical example of perfusion images is seen in Figure 1. All segmental scores were summed to produce a perfusion score (0–48) for each patient. WebThe 20-sector overlay permits the user to qualitatively assign a perfusion score to each segment for stress and rest. Difference scores for reversibility and summed scores for each polar map are automatically calculated. Rounding errors account for the apparent discrepancies between the reversibility polar map and the difference scores.
