Figure 3. 52-year-old man with gastric varix due to liver cirrhosis. (a) Source image of portal venous phase. (b) Source image after subtraction of an arterial phase image from a portal venous phase image shows that the signal of the aorta is completely eliminated, but enhancement of the left kidney is not entirely eliminated. (c) Non-subtraction three-dimension magnetic resonance portography (3D-MRP) image. (d) Subtraction 3D-MRP demonstrates effective suppression of the arterial signal and the enhancement of adjacent organs, even in these imperfect subtraction conditions. The portal collateral venous systems (arrows) are more clearly visualized compared with (c). (e) Retrograde balloon occluded venogram from the left adrenal vein also shows the gastric varix.
