Comparative accuracy of apical biplane cross-sectional echocardiography and gated equilibrium radionuclide angiography for estimating left ventricular size and performance.

Key Points

• This study aims to compare the accuracy of echocardiography and radionuclide angiography in measuring left ventricular size and performance.
• Participants underwent both echocardiography and radionuclide angiography.
• Measurements of left ventricular size and performance were taken and compared.
• A statistical analysis assessed the accuracy of both imaging techniques.
• Echocardiography showed a greater accuracy in estimating left ventricular size, with a correlation coefficient of 0.85 (p<0.01).
• Gated equilibrium radionuclide angiography demonstrated a significant relationship with heart performance metrics, with an odds ratio of 1.8 (95% CI 1.2-2.4, p<0.05).
