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. 3

Linear regression correlation: net flow values (ml) in the ascending aorta of both techniques by the two observers are plotted on both X-axis and Y-axis. The X-axis represents the four-dimensional (4D) method of flow analysis while the Y-axis represents the two-dimensional (2D) method of flow analysis in all four graphs. Graphs a and c represent healthy volunteers, b and d represent patients with bicuspid aortic valve (BAV). A line of identity (dashed) y = x is added. The regression line (solid) indicates the offset between the two methods
