Abidov A, Kang X, et al. Prognostic validation of a 17-segment score derived from a 20-segment score for myocardial perfusion SPECT interpretation. Web27 Jan 2013 · The Summed Rest Score (SRS) is the numerical score representing myocardial perfusion during rest and the Summed Stress Score (SSS) is the score calculated with exercise. The SRS identifies impaired perfusion at rest, generally areas of myocardium that are infarcted and not recoverable.

Web1 Oct 2010 · A summed difference score was given by the difference between SSS and SRS. A visually assessed total perfusion deficit (TPD) for CT-MPI was derived by dividing CT-MPI SSS by 68 (which represents the sum of the maximum scores that could be assigned to each of the 17 segments), an approach previously applied to SPECT-MPI (19). Web11 Jun 2024 · A summed perfusion score was obtained by adding the scores of the 20 segments of SPECT images: summed rest score, summed stress score, and summed difference score. A summed stress score <4 was considered normal, and a summed stress score ≥4 was considered abnormal. 3 Differences in summed perfusion scores from …
Web23 Mar 2024 · From normal (score = 0) to lacking perfusion (score = 4), each cardiac section was graded. The scores from the 17 stress image segments were added to get the summed stress score (SSS), representing the entire aberrant myocardium (i.e., necrotic and ischemic tissue).
