– 3D multimodality image fusion on live fluoroscopy

• Routinely adopted in interventional radiology

• TIPS with CBCT does not require :– a second radiologist (TIPS placement under US

guidance) – a percutaneous portal system puncture and

opacification for a 2D angiography acquisition to guide the portal branch puncture

– iodinated contrast media or CO2 wedge injection into a hepatic vein for 2D or 3D portography acquisition technics (risk of capsule rupture during wedge injection)

– iodinated contrast media IV injection

Discussion : Advantages

• 3D portal venous phase computed tomography image fusion with 2D fluoroscopy guidance for TIPS placement: feasible, efficient and safe

• By identifying virtual needle path, CBCT and pre-procedural CT image enable real time multiplanar guidance and facilitate TIPS placement
