In this episode of Rethink Imaging, host Chris St. John sits down with Tobias Gilk, an internationally recognized MRI safety expert and founder of The Invisible Force podcast. Moving beyond standard compliance checklists, Tobias exposes the critical gaps in modern MRI safety training, regulatory oversight, and physical environment workflows. From analyzing the fatal 2025 Long Island projectile accident to revealing how safety inefficiencies secretly drain facility revenue, this conversation provides a definitive blueprint for protecting patients while maximizing operational throughput.

In this episode of Rethink Imaging, host Chris St. John sits down with Tobias Gilk, a world renowned healthcare architect and certified MRI safety expert. Moving beyond the standard industry assumption that MRI is entirely risk free due to its lack of ionizing radiation, Gilk pulls back the curtain on the critical, unique physical hazards lurking inside the magnet room. From analyzing tragic projectile accidents to tracing why modern imaging workflows are fundamentally broken, this conversation explores how true safety in radiology requires rethinking the architecture of patient screening from the ground up.

In this episode of Frame by Frame: Rethink Imaging, host Chris St. John sits down with Dr. Tessa Cook, Vice Chair of Practice Transformation and Director of the Imaging Informatics Fellowship at Penn Medicine.
Moving beyond the standard industry hype surrounding artificial intelligence, Dr. Cook pulls back the curtain on the critical infrastructure required to make advanced technology actually work on the clinical front lines. From pioneering open-source radiation dose tracking to designing enterprise-wide patient follow-up systems, this conversation explores how true innovation in radiology always starts with solving the workflow problem, not just writing better code.

In this episode of Rethink Imaging, host Chris St. John sits down with Jill Shuman, a board-certified diagnostic medical physicist at the Marshfield Clinic, to pull back the curtain on the gritty reality of rural healthcare.
Far removed from the massive budgets of big academic institutions, Jill oversees imaging safety and quality across a broad network of underserved facilities in Wisconsin and Michigan. From fighting "break-fix" budget constraints to navigating the quality risks of a 100% traveler technologist workforce, Jill reveals what it truly takes to protect patient lives in a system that wasn’t built for small towns.

In this episode of Rethink Imaging, host Chris St. John sits down with Dr. M. Mahesh, a world-renowned medical physicist from Johns Hopkins, to deconstruct the myths and misinformation surrounding medical radiation.
Dr. Mahesh reveals how sensationalist headlines, like the "600% increase" in population radiation, often lack the scientific context necessary for patient safety. From the hidden dangers of lead shielding to how AI is changing the way we find health information, this conversation bridges the gap between academic "ivory towers" and the public’s need for clear, comforting, and accurate answers.

In part two of this deep dive, host Chris St. John and Dr. Mina Makary explore the "sci-fi" reality of modern interventional radiology. From ultrasound waves that destroy tumors without a single incision to embolization procedures that treat chronic pain and enlarged prostates, Dr. Makary reveals how the "fourth pillar" of cancer care is making major surgery a last resort rather than a first step.

In the first of a two-part series, host Chris St. John sits down with Dr. Mina Makary, a dual board-certified radiologist at The Ohio State University, to explore the rapidly evolving world of Interventional Radiology (IR). Dr. Makary clarifies the vital distinction between burnout and "moral injury" the psychological toll of being prevented from doing what is ethically right by systemic barriers, and advocates for a patient-centered approach that prioritizes transparency and minimally invasive options.

In this episode of Rethink Imaging, host Chris St. John sits down with Dr. Julie Bauml, a radiologist and clinical informatics expert, to dismantle the "replacement" narrative in medical AI. Dr. Bauml explains the concept of the "cognitive ceiling", the hard limit on human image processing, and argues that AI’s true value lies in automating the "non-doctoring" tasks to alleviate burnout rather than simply cranking up study volumes.
