Ep. 86 Exploring Advancements in Interventional MRI with Dr. David Woodrum and Joshua Krieger

Have you heard of interventional magnetic resonance imaging (iMRI)? In this episode of the BackTable Podcast, we dive into the exciting world of interventional MRI and its promising benefits for accessing previously difficult-to-reach biopsy and treatment areas. Host and interventional radiologist Dr. Kavi Krishnasamy is joined by Dr. David Woodrum, Director of the Interventional MRI Program at the Mayo Clinic, and Joshua Krieger, Director of Product Management at Cook Medical. --- SYNPOSIS The physician-industry trio discusses the history, current state, and future potential of interventional MRI, focusing on the advantages of low-field MRI in expanding access to imaging tools for patients—especially those with implants, hard-to-reach lesions, or concerns about radiation exposure. The group also explores how MRI is used for precise targeting and real-time monitoring in various medical procedures, including biopsy and ablation of liver and prostate lesions. Dr. Woodrum and Joshua share their experiences of integrating and streamlining interventional MRI into their department’s workflow. Throughout the conversation, Dr. Woodrum and Joshua emphasize the importance of collaboration between clinicians, interventional radiologists, and the industry in advancing this innovative field. They also speculate on future developments, such as the potential integration of angiography with low-field MRI technologies. --- TIMESTAMPS 00:00 - Introduction 02:10 - History and Evolution of Interventional MRI 09:08 - Current State of Interventional MRI 12:59 - Developments in Low Field MRI 21:31 - Availability of MRI-Compatible Devices 27:50 - Benefits of MRI Over Other Modalities 34:52 - Real-Time Imaging in MR vs. CT 40:48 - Clinical Confidence in MR-Guided Biopsies 42:44 - Future of MRI in Interventional Radiology 47:14 - Starting an Interventional MRI Service Line 57:05 - Potential of MR in Vascular Interventions --- RESOURCES Interventional MRI Symposium: https://imri2024.org/
