AB  - Left ventricular ejection fractions in 25 patients, as determined by first transit and R-wave synchronized imaging, were compared with contrast angiography. The ejection fraction obtained by first transit and R-wave synchronized images using a varying region of interest correlated well with the contrast angiography (r=0.96; r=0.99 respectively). Use of a fixed end-diastolic region of interest consistently underestimated the ejection fraction (r=0.92).
