Fig. 6From: The use of dedicated long-axis views focused on the left atrium improves the accuracy of left atrial volumes and emptying fraction measured by cardiovascular magnetic resonanceLeft atrial emptying fraction: comparison between methods. Comparison of left atrial emptying fraction (LAEF) obtained using the biplane area-length method applied to both the standard (top panels) and the LA-focused (bottom panels) cine images, with LAEF derived by the short-axis segmentation that were taken as referenceBack to article page
