Comparative StudyLeft ventricular function in patients with coronary artery disease assessed by gated tomographic myocardial perfusion images. Comparison with assessment by contrast ventriculography and first-pass radionuclide angiography.
This study evaluated the use of gated single-photon emission computed tomographic (SPECT) myocardial perfusion images for determination of left ventricular ejection fraction. ⋯ Semiautomated ejection fractions can be obtained from gated SPECT technetium-99m sestamibi perfusion images using the image inversion technique. These results are reproducible and correlate well with results of first-pass radionuclide angiography but are closer in value to those obtained with contrast ventriculography.
