Figure 11  Cardiac magnetic resonance imaging to calculate Qp:Qs. Regions of interest are placed in the aorta and main pulmonary artery (yellow and orange circles, respectively), and phase-contrast magnetic resonance imaging is performed. The graph shows the quantity and directions of flow at these levels. The flow parameters and Qp:Qs are shown in the system-generated table.
