Technetium-99m-methoxy isobutyl isonitrile multiple-gated radionuclide angiocardiography provides a reliable method for determining left ventricular ejection fraction that correlates well with established imaging techniques.
Davis et al. (1993) conducted an observational in Cardiac disease (n=23). Technetium-99m-methoxy isobutyl isonitrile multiple-gated radionuclide angiocardiography vs. Contrast X-ray single-plane cineangiography was evaluated on Correlation of left ventricular ejection fraction (r=0.83, p=<10(-6)). Left ventricular ejection fraction determined by technetium-99m-methoxy isobutyl isonitrile radionuclide angiocardiography correlated well with contrast X-ray cineangiography (r=0.83, p<10^-6).
