Artifacts in Quantitative analysis of myocardial perfusion SPECT, using Cedars-Sinai QPS Software

Hadi Malek et al. J Nucl Cardiol. 2017 Apr.

Abstract

Quantitative analysis of myocardial perfusion Single photon emission computerized tomography (SPECT) images is increasingly applied in modern nuclear cardiology practice, assisting in the interpretation of myocardial perfusion images (MPI). There are different extensively validated state-of-the-art software packages, including QPS (cedars-Sinai), Corridor 4DM (University of Michigan) and Emory cardiac toolbox (Emory university), providing highly accurate and reproducible data. However, these software packages may suffer from potential artifacts related to patient or technical factors. By recognizing the source of such artifacts, the interpreting physician can avoid misinterpretation of MPI study. In this review, we discuss some of technical pitfalls that may occur in Quantitative Perfusion SPECT software (QPS, cedars-Sinai Medical center).

Keywords: Artifacts; Cardiac-Gated single-photon emission computer-assisted tomography; Myocardial perfusion imaging.
