Abstract
Objectives：This study was performed to assess the accuracy of real-time three-dimensional echocardiography (RT3DE) multiplane imaging for measuring left ventricular (LV) volumes in vitro.
Methods：Twenty left ventricular phantoms in different shapes were made of balloons (including 12 normal LV phantoms and 8 LV aneurysm phantoms). The volumes of these phantoms were quantified by RT3DE multiplane imaging and conventional 2DE, respectively. The results were compared with the corresponding actual volumes determined by volumetric cylinder.
Results：In both 12 normal LV phantoms and 8 LV aneurysm phantoms, the LV volumes measured by RT3DE multiplane imaging correlated quite well with the actual ones. The agreements were pretty good between these two methods. And there were no statistical differences between them. In the same phantoms, although there were also good correlations between the LV volumes measured by 2DE and the actual volumes, the agreements were bad between these two methods. And whether in normal LV phantoms or in LV aneurysm phantoms, the LV volumes measured by 2DE were statistically different from the actual volumes (P<0.05).
Conclusions：Compared with 2DE, RT3DE multiplane imaging can quantify left ventricular volumes rapidly and accurately, which established the ground of assessing left ventricular function reliably.
