Figure 1. Ejection Fraction by Imaging Modality.

Figure 1

Histogram of measured ejection fraction, in increments of 5%, according to imaging modality. Ejection fraction measures are skewed toward higher values among patients who underwent measurement by radionuclide scan, whereas echocardiography and contrast angiography have more symmetric distributions.
