Figure 4

A 45-year-old female with intrahepatic portosystemic venous shunt with associated aneurysms. (a) Contrast enhanced coronal VIBE MRI showing communication between the right anterior portal vein branch (green arrow) and right hepatic vein through 28 mm aneurysm (blue arrow). (b) Coronal VIBE MRI (a few sections posterior to (a)) demonstrating communication between the right portal vein and right hepatic vein (red arrow) through a second, larger, 37 mm aneurysm (blue arrow). Protocol: Siemens, 1.5 Tesla Avanto MR Scanner, TR = 4.3, TE = 1.91, 3.5 mm slice thickness, Matrix = 256 × 256, with 15 mL Gadobenate dimeglumine (Multihance, Bracco Diagnostics Inc.) injection.
