Comparison of Three Commercially Available Softwares for Measuring Left Ventricular Perfusion and Function by Gated SPECT Myocardial Perfusion Imaging.
The three softwares, Quantitative Perfusion SPECT (QPS), Emory Cardiac Toolbox, and 4 Dimension-Myocardial SPECT (4DM) are widely used with myocardial perfusion imaging (MPI) to determine perfusion defect size (PDS) and left ventricular (LV) function.
