Synopsis

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.
