Fig. 3

Top row—3D sphericity indices (3DS) of two cases at maximum left atrial volumes. Detected volumes and left atrial surface area was used for 3D sphericity calculation. Pulmonary vein and left atrial appendage ostia, and mitral annular openings were included to LA surface area. Middle row—Wireframe models of 3D segmented left atria in blue. Best fitted spheres are shown in red for left atrial sphericity (LASP) calculation. Study subjects are same as in top row. Bottom row—Bland–Altman plots of left atrial sphericity and 3D sphericity. Red line indicates bias, yellow lines indicate limits of agreement (bias ± 2SD). Bottom row—Bland–Altman plots of left atrial sphericity and 3D sphericity. Red line indicates bias, yellow lines indicate limits of agreement (bias ± 2SD). 3DS 3D sphericity, LASP left atrial sphericity
