Assessment of diastolic function parameters with ECG gated myocardial perfusion spect: comparison of Two algorithms

ABSTRACT

Background: To compare Cedars-Sinai QGS and Michigan University Corridor4DM algorithms for determination peak filling rate [PFR], time to peak filling rate [TPFR] and mean filling rate in first third of diastole [MFR3] using 16 frames gated myocardial perfusion single photon emission computed tomography [SPECT]. To determine inter-observer reproducibility of Cedars QGS and Michigan University Corridor4DM for determination PFR, TPFR and MFR3 using 16 frames gated myocardial perfusion SPECT
