This study was aimed to analyze the value of the SPECT MPI to myocardial ischemia and cardiac function parameters in the CAD prognosis assessment. A total of 890 patients with suspected CAD underwent adenosine loading stress gated SPECT. At a mean follow-up of (2.3 +/- 0. 4) year, a total of 37 adverse events occurred, including 12 cardiac deaths and 25 nonfatal myocardial infarctions. Univariate Cox analysis showed that diabetes (wald 6.95, P < 0.01), SSS (wald 24.31, P < 0.001), EF (wald 17.14, P < 0.001), ESV (wald 8.58, P < 0.01) and EDV (wald 7.95, P < 0.01) were significant predictors of MACEs. Multivariate Cox analysis showed that SSS (wald 6.69, P < 0.05) and EF (wald 4.70, P < 0.05) were independent predictors. According to the results, SSS and EF are both independent predictors of MACEs.

PURPOSE: Abutted scatter energy windows used for a triple energy window (TEW) method may provide wrong estimation of scatter. This study is to propose an extended TEW (ETEW) method, which doesn't require abutted scatter energy windows and overcomes the shortcomings of TEW method. MATERIALS AND METHODS: The ETEW is a modification of the TEW which corrects for scatter by using abutted scatter rejection windows, which can overestimate or underestimate scatter. The ETEW is compared to the TEW using Monte Carlo simulated data for point sources as well as hot and cold spheres in a cylindrical water phantom. Various main energy window widths (10 %, 15 % and 20 %) were simulated. Both TEW and ETEW improved image contrast, % recovery coefficients and normalized standard deviation. RESULTS: Both of TEW and ETEW improved image contrast and % recovery coefficients. Estimated scatter components by the TEW were not proportional to the true scatter components over the main energy windows when ones of 10 %, 15 %, and 20 % were simulated. The ETEW linearly estimated scatter components over the width of the main energy windows. CONCLUSION: We extended the TEW method into the method which could linearly estimate scatter components over the main energy windows.
