99mTc-MIBI Miyokard Perfüzyon Sintigrafisi ile Değerlendirilen Kantitatif Verilerin, Koroner Arter Hastalığını Öngörme Kabiliyeti

Objective: Although the efficacy of visual interpretation 99mTc-MIBI myocardial perfusion imaging has been repeatedly confirmed in diagnostic and prognostic evaluation coronary artery disease (CAD), automated quantitative dependent on computer programs is controversial. In our study, we compared data, such as sum stress score (SSS) difference (SDS), with angiography results. We investigated ability SSS SDS values to predict disease. Method: are measurements used global scoring perfusion. While indicates degree ischemia, defines reversibility ischemia. perfusion, when was 4 above, MPI evaluated positive. angiography, a stenosis value >50% divided into three groups; mild (4-8), moderate (9-12), advanced (>13) hypoperfusion. two groups below above 10%. subsequent data results angiographies ( 70% stenosis). Results: A total 104 patients who underwent were included study. The accuracy detecting positivity between general methods calculated 80.8%. agreement found be significant (Kappa=0.602; p<0.001). When compared, but (Kendall's tau-b=0.373; p=0.014). Comparing groups, at low level tau-b=0.234; p = 0.014). Conclusion: had high predictive CAD, CAD detection rates detailed (SSS, SDS) not sufficient level. Therefore, suggest that alone will insufficient should complement evaluation.
