Fig. 9From: Time-resolved tracking of the atrioventricular plane displacement in Cardiovascular Magnetic Resonance (CMR) imagesCorrelation and bias for the atrial contraction, automatic tracking compared to manual measurements. Scatter plot of the atrial contraction in % of the AVPD in end systole (left panel) and the corresponding modified Bland-Altman plot (right panel) for the automatic tracking against manual measurements in n = 20 subjects. Top row shows results for the left ventricle and the bottom row shows the results for the right ventricle. The identity line is shown as a solid line in the scatter plots, and linear regression as a dashed line. In the modified Bland-Altman plots the mean bias is shown as a solid line with limits of agreement (±2SD) as dashed lines. Correlation R value was 0.49 for the left ventricle, and 0.39 for the right ventricle. For the left ventricle, mean bias was −1.5% with limits of agreement between −20.9 and 17.9%. For the right ventricle, mean bias was 3.3% with limits of agreement between −14.3 and 20.9%Back to article page
