- W1867496239 abstract "2051 Objectives Mismatched finding between iodinated fatty acid analogue 123I-β-methyl iodophenyl-pentadecanoic acid (BMIPP) and 201Tl (thallium) images has provided additional value for prediction of major adverse cardiac events. However, visual semi-quantitative analysis on dual SPECT is too ambiguous to detect the mismatch region.The purpose of this study is to construct the algorithm for evaluating the mismatched region based on quantitative myocardial analysis software and to compare this automated analysis with visual analysis on dual SPECT. Methods We examined 96 patients who underwent dual SPECT using 123I-BMIPP and 201Tl from the 2009 April to September in this study. The Uptake on SPECT images was visually graded on a 5-point scale (0 normal, 4 absent) in 17 segments and assessed as summed BMIPP or Tl scores. The mismatched score was calculated as follows: summed BMIPP minus Tl scores. The % area of the mismatched region was calculated on polar map of count-normalized dual isotope images. Results There was a good correlation between visually-calculated mismatch scores and the % area of the mismatched region on software(r=0.82, p Conclusions The software-based analysis is objective and useful for evaluating the mismatch region quantitatively on dual 123I-BMIPP and 201Tl Myocardial SPECT" @default.
