Do nuclear angiographic methods accurately measure left ventricular ejection fraction compared to contrast ventriculography in patients with ischaemic heart disease?
A modified gated nuclear angiography method provides a useful non-invasive means for assessing left ventricular function, correlating well with contrast ventriculography.
Muir et al. (1977) studied this question.
