title: MRI of TIPS with covered stent-grafts: In vitro analysis using a flow phantom and initial clinical experience.
abstract: OBJECTIVE
  The use of the Viatorr stent-graft for transjugular intrahepatic portosystemic shunt (TIPS) creation is thought to improve patency rates. This study was designed to show the feasibility and pitfalls of imaging Viatorr TIPS using MRI.
  
  
  CONCLUSIONS
  MRI of the Viatorr stent-graft is feasible for the initial assessment of the TIPS. Familiarity with the imaging patterns will allow proper interpretation of the MRI findings. MRI also allows the depiction of detailed anatomic information concerning stent positioning.
