Web29 Mar 2006 · The summed rest score (SRS) and summed difference score (SDS) reflect resting perfusion abnormalities and the change between the stress and rest perfusion scores, respectively. We have previously shown that there is close agreement between the visual and automated quantitative assessment in terms of diagnosis and prognosis [10, 16]. 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). saxion home https://edgegroupllc.com
