| 6/25/26 | ![]() Photon Counting CT Could Revolutionize Diagnostic Radiology | In this episode of Rethink Imaging, host Chris St. John sits down with Dr. Aaron Sodickson, Division Chief of Emergency Radiology at Mass General Brigham and Associate Professor at Harvard Medical School, to pull back the curtain on how advanced CT technology is transforming patient care. Moving from standard grayscale imaging to full-body photon counting scanner operations, Dr. Sodickson reveals what it takes to bring cutting-edge clinical technology out of the development lab and onto the front lines of emergency medicine. From slicing patient radiation dose in half to wiping out diagnostic uncertainty, this conversation explores the massive leap forward in clinical radiology. | 40m 39s | ||||||
| 6/11/26 | ![]() Medical Physics in Rural Hospitals: Higher Dose, Lower Resources, Bigger Stakes | 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. | 36m 52s | ||||||
| 5/28/26 | ![]() Are CT Scans Safe? What Most People Get Wrong About Radiation | 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. | 53m 49s | ||||||
| 5/14/26 | ![]() Killing Tumors Without Chemo: Sci-Fi Treatments Already in Hospitals with Dr. Mina Makary | 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. | 30m 24s | ||||||
| 4/30/26 | ![]() It’s Not Just Burnout: What’s Also Affecting Radiologists with Dr. Mina Makary | 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. | 39m 29s | ||||||
| 4/16/26 | ![]() The Cognitive Ceiling: Why AI Must Support Radiologists, Not Replace Them | 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. | 45m 48s | ||||||
| 4/2/26 | ![]() The Triple-Certified Technologist: Fixing Radiology’s 20% Workforce Gap | In this episode of Rethink Imaging, host Chris St. John speaks with Chalonda Jones-Thomas, founder of the Thomas Institute of Health Professions, about the urgent need to modernize medical imaging education.

| 3/19/26 | ![]() 45% Fewer Autopsies: How Postmortem CT Is Changing Death Investigation in the U.S. | What if nearly half of traditional autopsies could be avoided without sacrificing diagnostic certainty? In this episode of Rethink Imaging, host Chris St John speaks with Dr. Kalpana Kanal, Director of Diagnostic Physics at the University of Washington, and Dr. Jonathan Medverd, Chief of Radiology at Harborview Medical Center, about building one of the most advanced postmortem CT programs in the United States. Together, they share how a cross-campus collaboration between radiology and the medical examiner’s office has scanned 184 cases to date, avoided autopsy in approximately 45% of them, and demonstrated how virtual autopsy can improve efficiency, reduce costs, respect religious objections, and enhance forensic investigations. This conversation explores clinical validation, operational hurdles, PACS integration, billing challenges, and the long-term vision for forensic radiology fellowships in the U.S. | 40m 13s | ||||||
| 3/5/26 | ![]() Total Risk in CT Imaging: Why Clinical Risk Outweighs Radiation Risk with Dr. Francesco Ria | In this episode of Rethink Imaging, host Chris St. John sits down with Dr. Francesco Ria to explore a critical but often misunderstood concept in CT imaging: total risk. While radiation dose often dominates conversations around CT safety, Dr. Ria explains why clinical risk including missed diagnoses, delayed treatment, and underutilized imaging — frequently outweighs radiation risk when exams are not properly justified or optimized. The conversation reframes how imaging professionals, clinicians, and leaders should think about safety, appropriateness, and value in modern CT practice. Rather than focusing narrowly on dose reduction, Dr. Ria advocates for a more balanced approach that prioritizes diagnostic quality, patient outcomes, and evidence-based decision-making across the imaging pathway. | 40m 28s | ||||||
| 2/19/26 | ![]() How Viruses Reshape the Brain: Imaging Neuroinflammation and Cancer Pathways with Claudia Kirsch | Dr. Claudia Kirsch joins Rethink Imaging to discuss how viruses like SARS-CoV-2 reshape the brain through inflammation, vascular injury, and immune pathways.
