Bland-Altman analysis. Bland-Altman plots comparing (a) net flows in six contours and (b) peak velocities in the aortic root of S2 and compressed sensing (CS) accelerated scans. Data from different contours are indicated by different markers. The mean differences, standard deviations and their confidence intervals (red shaded areas) were calculated from the data points of all contours. The red data points denote the data of the volunteer whose net flow curves are shown in Fig. 2. The mean differences in net flow (a) between S2 and CS increase with increasing CS acceleration factor, while the standard deviations of the mean differences remain almost constant. The peak velocities (b) tend towards negative biases for all CS acceleration factors, while only exceeding the confidence interval of the mean difference for CS8. The standard deviation of the mean difference increases with increasing acceleration factor
