Gated cardiac MRI: ejection-fraction determination using the right anterior oblique view.
Fifteen adults underwent gated cardiac MR scans in the right anterior oblique position. End-diastolic and end-systolic images were acquired in an imaging plane parallel to the ventricular septum using spin-echo image acquisition on a 0.35-T system. Analysis of ventricular volumes and ejection fractions was performed using the area-length method. These results were correlated with ejection fractions obtained from angiocardiography. The linear regression line obtained for ejection fraction was y = 0.74x + 16 and the r value was 0.789, indicating a reasonable correlation between the two methods.
