Interventional MRI technology has been used to guide and monitor renal ablation procedures because of its ability to provide online feedback on ablation progress and determine treatment endpoints based of individual tumor responses. The field of Interventional MRI lacks the abundance of outcome data that provide the evidence for the added value of using MRI technology to guide interventions. We report the long-term efficacy data for interactive guidance and real-time monitoring of 46 renal ablation procedures performed entirely within an interventional MRI suite using a short introducing needle and a flexible laser fiber.
