From: Intraindividual validation of 4D flow measurement against 2D flow measurements in complex flow patterns in routine clinical cardiovascular magnetic resonance of bicuspid aortic valve

Fig. 4

Bland Altman plots: the Y-axis represents the individual differences of the ascending aorta net flow (ml) measurements by the two methods; two-dimensional (2D) and four-dimensional (4D) flow analysis by the two observers (upper two rows). In the lower row Y-axis represents the individual differences of the interobserver variability of the ascending aorta net flow measurements by the 4D method. X-axis represents the mean. Graphs a, c, and e represent healthy volunteers, and graphs b, d, and f represent patients with bicuspid aortic valve (BAV)
