Key result
Real-time triplane echocardiography (RTTPE) yielded left ventricular volume and ejection fraction measurements that were not significantly different from cardiac MRI, with excellent correlations.
Why the study?
Do 1-D, 2-D, and 3-D echocardiographic methods accurately quantify left ventricular volumes and ejection fraction compared to cardiac MRI in healthy dogs?

Real-time triplane echocardiography provides accurate measurements of left ventricular volumes and ejection fraction in dogs, comparable to cardiac MRI, making it a suitable method for routine veterinary cardiology.
Meyer et al. (2013) conducted an observational in Healthy (n=10). Real-time triplane echocardiography (RTTPE) vs. Cardiac MRI (CMRI) was evaluated on Left ventricular end-diastolic volume (EDV) in mL (p=0.16). Real-time triplane echocardiography (RTTPE) yielded left ventricular volume and ejection fraction measurements that were not significantly different from cardiac MRI, with excellent correlations.
