Does freehand three-dimensional echocardiography improve the accuracy and variability of left ventricular mass measurement compared to conventional methods in explanted human hearts?
Freehand 3D echocardiography provides highly accurate and reproducible measurements of left ventricular mass, particularly in abnormally sized or shaped hearts, compared to conventional methods.
Freehand three-dimensional echocardiography for measurement of left ventricular mass has high accuracy and low variability and is superior to conventional methods in hearts of abnormal size and geometry.
Gopal et al. (1997) studied this question.
