Comparison of left ventricular ejection fraction values obtained using invasive contrast left ventriculography two-dimensional echocardiography and gated single-photon emission computed tomography

摘要

Objectives:Left ventricular ejection fraction can be measured by a variety of invasive and non-invasive cardiac techniques. This study assesses the relation of three diagnostic modalities to each other in the measurement of left ventricular ejection fraction: invasive contrast left ventriculography, two-dimensional echocardiography, and quantitative gated single-photon emission computed tomography.
