QPS (Quantitative Perfusion SPECT) is an interactive application for the automatic segmentation, quantification, analysis & display of myocardial perfusion SPECT. New Features Improved Perfusion Quantification, or PFQ A more accurate quantitative perfusion analysis is the key advantage of PFQ, the improved quantification module of QPS. This software provides as its primary nuclear variable the Total Perfusion Deficit (TPD), reflecting the extent and severity of the overall perfusion defect, and correlating strongly with the widely used visual variables of SSS or % myocardium abnormal. PFQ has been shown to be superior to the previous quantitative algorithm of QPS and even to be able to outperform expert visual analysis, despite the fact that the experts take into account information from the patient’s history and stress test results in forming their final interpretation (Slomka, et al J Nucl Cardiol 2005;12:66-77). If this is accomplished in the expert laboratory, the importance of PFQ in less experienced laboratories is likely to be even more significant. PFQ also allows a greatly simplified addition of new perfusion databases.
