Single-Beat Versus Multibeat Real-Time 3D Echocardiography for Assessing Left Ventricular Volumes and Ejection Fraction

Abstract

Compared with conventional multibeat acquisitions, 2-beat modality provides similar accuracy in LV volume and EF measurements and should be preferred due to fewer stitching artifacts. In contrast, the temporal resolution of single-beat modality appears insufficient to provide an accurate estimation of LVEF.
