title: Examination and comparative study of a simple method to determine the left ventricular ejection fraction.
abstract: The authors developed a simple radioisotopic method for determining the left ventricular ejection fraction with 99mTc-labelled red blood cells. The semi-quantitative data is acquired at the equilibrium stage and gated to the ECG. The results of this atraumatic and reproducible isotopic determination of LVEF correlate statistically well those of echocardiography and left ventricular angiography.
