May support noninvasive EF assessment clinically; leaves open prospective validation in broader cohorts.
How do first pass radionuclide angiocardiography and M-mode echocardiography compare to contrast angiocardiography for assessing left ventricular ejection fraction?
First pass radionuclide angiocardiography and M-mode echocardiography provide comparable noninvasive assessments of left ventricular ejection fraction that correlate well with invasive contrast angiocardiography.
Albrechtsson et al. (1982) studied this question.
