1 From the Departments of Diagnostic and Interventional Radiology (H.H.Q., H.K., S.B., J.F.D., M.E.L.), Transplantation Surgery (G.K.), and Pathophysiology (S.A.), University Hospital Essen, Hufelandstr 55, D-45122 Essen, Germany. Received August 5, 2002; revision requested October 8; revision received January 29, 2003; accepted March 11. Supported by DFG grant no. LA 1325/1–1. Address correspondence to H.H.Q.

A floating table was integrated into a setup for performance of interventional magnetic resonance (MR) angiography procedures with actively visualized catheters and biplanar real-time image fusion. The setup was evaluated by performing catheterizations in eight pigs. The floating table enabled the authors to follow actively visualized instruments in the pigs’ vasculature during MR imaging–guided interventional angiography procedures while performing real-time biplanar MR imaging. Interventional MR angiography with a floating table enables the field of view to be moved along with the instrument tip to the region of interest and thus enhances the usability and flexibility of the interventional MR imaging setup.
