Abstract

The reproducibility of ejection fraction measurements has been studied using gated equilibrium blood pool scintigraphy. The use of appropriate statistical tests is proposed and commented upon. The intra-observer variability for our group of patients has a standard deviation of 6.4%, the interobserver variability of 3.2% and sequential studies done on the same and different days give standard deviations (due to “time” alone) of 1.0% and 1.9%, respectively. Different factors and sources involved in variability are mentioned. Variability values reported in the literature are discussed.
