MR images of main PA for a representative subject. a Sagittal image of the MPA displaying the location of 2D-PC acquisition slice. The imaging plane is prescribed in a double-oblique plane perpendicular to the flow direction. b 2D-PC magnitude image of the main PA, used to define and measure the cross-sectional area. c 2D-PC phase image, used to calculate the blood flow velocity, of the MPA. Grayscale-bar represents flow velocity in the phase image (ranges from -150 cm/s to 150 cm/s)
