A rapid method for standardization of the gated radionuclide left ventricular ejection fraction.
Radionuclide ventriculography has become the standard method for serially evaluating left ventricular ejection fraction (EF). The "gold standard" for evaluating EF is the contrast ventriculogram, which uses mathematical models to arrive at the volumes used to calculate EF. These models are subject to possible error. This paper reports the standardization of volume measurements of a digital angiographic camera system using a series of cardiac phantoms and the correlation of measurement of the EF of a series of patients whose EF was determined by digital angiography and radionuclide ventriculography.
