WebThe ejection volume divided by the end-diastolic volume is the ejection fraction. The formula used is the Tiecholz formula which is based upon the spherical volume of the heart multiplied by a correction factor. Since the volume of a sphere is the cube of the radius, and the left ventricle is almost a sphere, a correction factor to account for ... WebMar 26, 2015 · Objective: Assessment of ejection fraction (EF) results from Simpson’ method from 2D and 3D transthoracic echocardiography (TTE). In addition, it was also assessed stroke volume (SV) from 2D TTE and 3D TTE. Background: The reference method to calculate LV volumes, SV and EF is cardiac magnetic resonance imaging (MRI). …
