  • Title: Evaluation of portable radionuclide method for measurement of left ventricular ejection fraction and cardiac output.
    Author: Berndt T, Alderman EL, Wasnich R, Hsieh SC, Van Dyke D, Harrison DC.
    Journal: J Nucl Med; 1975 Apr; 16(4):289-92. PubMed ID: 1089771.
    Abstract:
    Seventeen patients with coronary artery, valvular, or myopathic heart disease were studied to determine correlations of the cardiac output and ejection fraction when comparing the results obtained with a portable probe technique using 113mIn with those obtained with standard methods (cineangiographic, Fick, and dye dilution). With ejection fractions ranging from o.10 to 0.85, the coefficient of correlation was 0.90 when comparing cineangiographic and radionuclide techniques. Cardiac output determinations by the radionuclide technique also correlated well with standard methods (r equals 0.88). The radionuclide method shows promise as an accurate, safe, and simple method in the evaluation of cardiac function at the bedside.
