Comparative Study[Assessment of left ventricular function and volume by myocardial perfusion scintigraphy--comparison of two algorithms].
Left ventricular volume and function can be computed from gated SPECT myocardial perfusion imaging using Emory Cardiac Toolbox (ECT) or Gated SPECT Quantification (GS-Quant). The aim of this study was to compare both programs with respect to their practical application, stability and precision on heart-models as well as in clinical use. ⋯ GS-Quant and ECT are two reliable programs in estimating LVEF. Both seem to underestimate the cardiac volume. In practical application GS-Quant was faster and easier to use. ECT allows the user to define the contour of the ventricle and thus is less susceptible to artifacts.
