From: 4D flow MRI of the aorta becomes practical: performance and observer variability for a new semi-automated workflow for 3D visualization and quantification of aortic hemodynamics

Figure 1

The upper row of the figure illustrates the steps 1 - 4 of the new standardized semi-automated workflow including the automated calculation of the 3D PC-MRA, the positioning of the 9 analysis planes equally distributed along the aorta, the flow visualization by calculating time-resolved pathlines and the flow quantification by determining peak velocity, net, forward,and reverse flow as well as regurgitation. The second row shows the Blant-Altman plots of peak velocity and net flow for the two observers summarized for 3 analysis planes.
