  • Figure 1
    Coronal MR angiography of the IVC

    MIP image illustrating the left IVC (arrow), and the abnormal venous drainage of liver segments V-VI to the right renal vein (small arrows). [A = aorta, az = azygos vein, arrowhead = right brachiocephalic vein]

     
    Area of Interest: unknown; Imaging Technique: Coronal MR angiography of the IVC;
