Key result
Three-dimensional echocardiography with a fast-rotating transducer strongly correlated with MRI for measuring LV end-diastolic volume (r=0.99), end-systolic volume (r=0.96), and ejection fraction (r=0.93).

May support rapid LV volumetry in cardiac patients; leaves open whether it can supplant MRI in routine practice.

Does a new fast-rotating 3DE transducer with semi-automated border detection accurately measure left ventricular volume and function compared to MRI in cardiac patients?
Effect estimate: r = 0.99 for LVEDV, r = 0.96 for LVESV, r = 0.93 for LVEF
A new fast-rotating 3DE transducer with semi-automated border detection provides rapid and accurate measurements of left ventricular volume and function that correlate strongly with cardiac MRI.
Krenning et al. (2006) conducted an observational in Cardiac disease (n=15). Three-dimensional echocardiography with a fast-rotating transducer and semi-automated border detection vs. Magnetic resonance imaging was evaluated on Left ventricular end-diastolic volume, end-systolic volume, and ejection fraction (r = 0.99 for LVEDV, r = 0.96 for LVESV, r = 0.93 for LVEF). Three-dimensional echocardiography with a fast-rotating transducer strongly correlated with MRI for measuring LV end-diastolic volume (r=0.99), end-systolic volume (r=0.96), and ejection fraction (r=0.93).
