Global and regional evaluation of systolic and diastolic left ventricular temporal parameters using a novel program for ECG-gated myocardial perfusion SPECT--validation by comparison with gated equilibrium radionuclide angiography and speckle-tracking radial strain from echocardiography.

Abstract

BACKGROUND A newly developed program, named cardioGRAF, enabled the evaluation of left ventricular (LV) systolic and diastolic temporal parameters for the estimation of heart failure using ECG-gated myocardial perfusion SPECT (GMPS). OBJECTIVE The feasibility of those global (g-) and regional (r-) parameters was validated to compare with gated equilibrium… (More)
