Real-time magnetic resonance guidance of interventional electrophysiology procedures with passive catheter visualization and tracking.

摘要

One of the key problems in interventional electrophysiology (EP) today is the inability to generate sufficient soft tissue contrast for intraprocedural visualization of the myocardium and the surrounding tissue by using conventional imaging techniques. Intraprocedural magnetic resonance imaging (MRI) has been identified as a potential solution to address this weakness of conventional EP; however, clinical adoption of MR-guided EP requires the development of EP devices that are both fully MR functional and MR safe at the same time.
