Nijran Background Estimation of the left ventricular ejection Conclusion There was a clinically significant difference fraction (LVEF) using myocardial perfusion imaging is between the LVEF calculated by QGS and 4DM-SPECT increasingly used in the evaluation of coronary artery and consequently the two packages should not be used disease. This study aims to compare the effect of (i) two interchangeably. The effect of cut-off frequency on LVEF commercially available software packages: quantitative estimation was found to be very patient specific. Changing gated single-photon emission computed tomography the cut-off frequency by as little as 0.1 cycles/cm can cause (SPECT) (QGS) and 4DM-SPECT, and (ii) prereconstruction clinically significant differences in LVEF estimation. filtering, on LVEF quantification.
