Coronal postcontrast twist sequence (time resolved gadolinium enhanced MRI) with multiphase following intravenous injection of gadopentetate dimeglumine. Arterial phase evaluation of the abdomen demonstrated a definite change in caliber of the abdominal aorta at the level of the midliver with narrowing of its subdiaphragmatic portion (long arrow). Additionally, between the IVC and the aorta, in the region of the left lobe of the liver, a vascular structure fills the left lobe of the liver (short arrow), communicating with a large left hepatic vein draining into the right atrium.
