The world of medical imaging is often discussed through the lens of cutting-edge academic research, but the majority of America's healthcare landscape relies on rural facilities operating on razor-thin margins. Jill Shuman, DMP, joins the podcast to share her boots-on-the-ground experience driving through a multi-hour radius to keep local scanners compliant, safe, and operational.Jill shares the harsh reality of spending years on "break-fix" budgets, where critical imaging equipment can only be replaced if it is entirely beyond repair—a cycle that leads to higher radiation doses for patients and increased system downtime. The conversation dives deep into the administrative and logistical hurdles unique to rural settings, including the influx of traveller technologists who frequently miss scanning fundamentals, the lack of rideshare infrastructure preventing patient access, and a punishing reimbursement system that creates a financial catch-22 for struggling community hospitals. It’s a powerful look at how local healthcare advocates fight for their neighbors, proving that personalized medicine in rural America is built on deep communal bonds.What You’ll Learn:The Break-Fix Cycle: How restrictive equipment budgets unintentionally lead to higher CT doses and increased scanner downtime.The Traveler Tech Paradox: The clinical and image quality risks that emerge when rural hospitals are forced to staff facilities 100% with temporary agency technologists.The Rural Catch-22: How CMS dose metrics and reimbursement penalties disproportionately punish underfunded hospitals with older equipment.Innovating on a Budget: How the Marshfield Clinic became the first in Wisconsin to adopt contrast-enhanced mammography, drastically lowering patient costs while matching MRI accuracy.The Reality of Access: Why the closure of rural hospitals creates devastating gaps in community health, and how physicists ground themselves in the human story behind the data..Chapters:[00:00] The Precariousness of Rural Healthcare: Jill shares the sobering reality of driving past a newly shuttered local hospital on her daily commute, highlighting the fragility of small-town medicine.[03:34] The Three Hats of a Rural Physicist: From splitting time between equipment testing and compliance paperwork to the daily "detective work" required to troubleshoot unexpected clinical issues.[06:52] Medical Physics 3.0 in Small Towns: Overcoming the industry misconception that outlying facilities cannot provide deeply personalized, high-level clinical care.[10:49] Budget Barriers and the Traveler Influx: How thin financial margins force rural clinics to balance lower patient volumes against the training risks of short-term agency staff.[13:30] The Break-Fix Reality: Jill details the hidden costs of aging machines and shares a case study of immediate image quality issues caused by a 100% traveler workforce.[16:12] No Uber, No Lyft: Navigating severe transportation hurdles and geography to get patients to specialized imaging appointments.[18:01] Entering the "Donut of Truth": Discussing high-utilizer CT scans, emergency room dynamics, and the rise of medical imaging meme culture on social media.[23:45] The Reimbursement Trap: Why penalizing higher-dose, older scanners via federal metrics hits thin-margin community centers the hardest.[27:44] Celebrating Huge Wins: How the Marshfield Clinic became the first hospital in Wisconsin to adopt low-cost, high-accuracy contrast-enhanced mammography.[33:40] Shouting for Resources: A final plea for financial grants, structural support, and updated protocol tools from the AAPM to assist rural physicists.Frame by Frame: Rethink Imaging Podcast is handcrafted by our friends over at: fame.so

The fear of radiation is often rooted in what we cannot see, smell, or touch, leading the public to associate life-saving CT scans with historical disasters like Hiroshima or Chernobyl. Dr. M. Mahesh, a Professor of Radiology and clinical leader, joins the podcast to combat this "infodemic" of medical disinformation.Dr. Mahesh shares his experience leading national reports on radiation exposure, explaining why a reported "600% increase" in the US population's dose was a misunderstood statistic that triggered unnecessary Congressional hearings. He dives into the counterintuitive science of why patient shielding, once a standard practice, can actually increase radiation doses due to modern automatic exposure controls. Beyond the physics, the episode explores the "long game" of building public trust through social media, the role of technologists as the "window for radiology," and how experts can "flood the zone" with good information to ensure AI models provide accurate medical adviceWhat You’ll Learn:The 600% Myth: How statistics about US radiation exposure were sensationalized and the reality of the 20% decrease seen in more recent years.The "Light Bulb" Analogy: Why an X-ray room holds zero radiation the second the machine is turned off.The Shielding Paradox: Why lead aprons can sometimes obscure clinical images or force machines to output more radiation.Combatting "Clickbait" Science: Strategies for clinicians to use social media and "comic book" storytelling to simplify complex safety concepts.The Role of AI: Why professionals must engage online to ensure Large Language Models (LLMs) prioritize accurate medical data over "scare tactics".Chapters:[00:00] The Headline That Horrified Congress: Deconstructing the 600% radiation increase report.[01:55] The Professional Obligation: Why Dr. Mahesh steps out of the academic "ivory tower" to speak to the public.[06:38] Communicating in "Multiple Languages": Explaining radiation to everyone from radiologists to grandmothers.[11:53] The MAMO Scare: How local news cycles turn life-saving screenings into fear-based clickbait.[23:26] Radiation Myths: Addressing the "Hiroshima reference point" and the light bulb analogy.[31:22] The Window of Radiology: Why technologists are the most important communicators in the clinic.[37:01] The Death of Shielding: The scientific evidence against using lead aprons for patients.[48:12] Advice for Professionals: How to start your own journey in public advocacy.

The field of radiology is at a breaking point, facing a massive "volume crush" that threatens to push professionals toward early retirement. Dr. Julie Bauml, a board-certified radiologist who transitioned into clinical informatics, joins the show to discuss why technology must be reframed as a tool for augmentation rather than a replacement for human expertise.The episode explores the "cognitive ceiling", a biological limit on how many high-level decisions and visual inputs a brain can process in a day. Dr. Bauml shares sobering anecdotes of AI tools implemented without radiologist input, resulting in poor workflow integration and even decreased reimbursement. From the "Minority Report" dream of hands-free, spatial computing to the nuances of "ground truth" in clinical data, this conversation is a tactical roadmap for how to keep radiologists meaningfully in the loop while leveraging AI to handle the rote, draining tasks that lead to burnout.What You’ll Learn:The Cognitive & Visual Ceiling: Understanding the biological limits of human image interpretation and decision-making.Augmentation over Replacement: Why the 10-year-old narrative of "obsolete radiologists" failed and where the industry is moving now.The "Non-Doctoring" Tasks: Identifying workflow bottlenecks—like chart searching and window alignment—that AI is best suited to solve.The Ground Truth Complexity: Why "weak labels" and human variability make training medical AI harder than standard machine learning.Spatial Computing in Radiology: How VR and AR could solve ergonomic injuries and liberate radiologists from the "giant monitor" setup.Chapters:[02:24] The Career Pivot: Transitioning from clinical practice to informatics to save the "spark" of radiology.[04:05] The Volume Crush: Why the fee-for-service structure and high volume create an interdependent crisis.[06:01] Defining the Ceiling: The visual cortex limit—you can't just "tape your eyes open" to read more.[09:43] The Replacement Myth: Why early AI "point solutions" alienated the workforce.[14:39] Seat at the Table: The importance of including MDs in industry leadership and product design.[19:11] Implementation Failures: An anecdote on how poorly integrated tools can actually make a backlog worse.[25:03] Ground Truth & Data Quality: Why "more data" isn't the answer to baking a better clinical "cake".[41:00] Spatial Computing: The future of hands-free radiology and reading cases from anywhere.Frame by Frame: Rethink Imaging Podcast is handcrafted by our friends over at: fame.so

The medical imaging workforce is facing a critical shortage, with CT tech vacancy rates reaching nearly 20%. Chalonda Jones-Thomas identifies a primary cause for the struggle: a disconnect between outdated textbooks and the rapid advancement of real-world imaging technology. To address this, Chalonda developed the first fully online CT and MRI training programs designed specifically for medical imaging professionals.The episode explores the operational and pedagogical shifts required to move training into a digital space. Chalonda explains how her programs use video, simulation software, and rigorous checkpoints to ensure students are clinically competent before ever touching a patient. By removing geographical barriers, these programs provide a lifeline for technologists in rural areas and military personnel stationed overseas who need civilian-ready credentials. Chalonda reframes online education not as a "hands-off" experience, but as a flexible, data-driven system that empowers technologists to upskill without putting their lives or careers on hold.What You’ll Learn:The Textbook Lag: Why traditional education materials are falling behind the rapid pace of CT and MRI technology.Proving Online Integrity: How simulation software and rigorous assessments won over skeptical radiologists and directors.Empowering the Underserved: How online education provides advanced imaging paths for rural technologists and working parents.Military-to-Civilian Transition: The role of remote learning in helping military personnel translate their service experience into civilian healthcare careers.Modern Workforce Solutions: Why flexible education models are the key to solving the national technologist shortage.Chapters:[05:13] The Textbook Disconnect: Recognizing that technology moves faster than the classroom can keep up.[10:38] Validating Online Learning: Implementing assessments and simulations to ensure clinical readiness.[14:08] Reaching the Rural Technologist: Providing advanced education to those who cannot travel to a physical campus.[15:10] The Military Angle: Helping service members earn certifications while stationed abroad to prepare for civilian entry.[21:50] Future Pathways: The development of entry-level gateways like MRI Assistant programs.Frame by Frame: Rethink Imaging Podcast is handcrafted by our friends over at: fame.so

Postmortem CT is not theoretical. It is operational and growing.In this episode of Rethink Imaging, Dr. Kalpana Kanal and Dr. Jonathan Medverd share the real-world story behind launching a collaborative forensic imaging program between the University of Washington and King County’s Medical Examiner Office. What began as a pilot project six years ago has evolved into a structured clinical pathway that has scanned 184 decedents since July 2022.The results are striking. In roughly 45% of cases, CT findings were sufficient to determine cause of death, eliminating the need for traditional autopsy. In early validation cases, imaging diagnoses including precise identification of a ruptured aorta were confirmed at autopsy, demonstrating strong radiologic-pathologic correlation.Beyond clinical accuracy, the episode dives into the operational realities: aligning two different governance structures, navigating IT firewalls between hospital PACS and county systems, securing funding for scanner installation, building trust between specialties, and operating without a billable CPT code for postmortem imaging. The conversation is candid about volunteerism, resource constraints, and the importance of leadership commitment before launching similar programs.The broader implications are significant. Postmortem CT offers cultural and religious alternatives for families who object to invasive autopsy. It reduces pathologist exposure to infectious diseases and toxic embalming chemicals. It may improve courtroom communication by replacing graphic imagery with diagnostic imaging. And it opens the door to cost efficiencies, particularly when complex autopsies can exceed $2,500 per case.Looking ahead, Dr. Kanal and Dr. Medverd discuss developing a forensic radiology rotation for senior residents and the longer-term vision of a dedicated fellowship combining radiology and forensic pathology expertise. As forensic pathology faces workforce shortages nationwide, hybrid training models may become essential.This episode reframes postmortem CT not as a niche innovation, but as a scalable systems solution with implications for public health, forensic science, radiology training, and healthcare economics.What You’ll Learn:How postmortem CT can replace traditional autopsy in ~45% of casesThe radiologic-pathologic validation process behind virtual autopsyOperational hurdles when partnering between hospital and county systemsHow PACS, DICOM storage, and EMR access were structured across entitiesThe billing and CPT code gap limiting U.S. adoptionCultural and religious considerations in death investigationCost comparisons between CT and complex autopsyWhy forensic radiology fellowships may represent the next evolutionChapters:[00:00] The First Postmortem CT Case That Changed Everything[05:35] Radiology–Medical Examiner Collaboration in Practice[12:07] 184 Cases and a 45% Autopsy Avoidance Rate[18:00] Diagnostic Challenges: Decomposition vs. Trauma[23:29] Building a Forensic Radiology Rotation[29:19] IT, PACS, and Cross-Entity Data Sharing[32:35] Why Billing Codes Are Holding the U.S. Back[34:37] Cost Comparisons and Public Health Impact[36:46] How Counties Can Replicate the ModelFrame by Frame: Rethink Imaging Podcast is handcrafted by our friends over at: fame.so

Radiation risk has long shaped how clinicians and patients think about CT imaging. But according to Dr. Francesco Ria, focusing on radiation alone misses the bigger picture.In this episode of Rethink Imaging, Dr. Ria introduces the concept of “total risk” — a framework that considers not only radiation exposure, but also the clinical consequences of missed or delayed diagnoses, unnecessary repeat scans, suboptimal image quality, and inappropriate utilization. When CT exams are avoided out of disproportionate fear of radiation, patients may face far greater harm from undiagnosed disease.Dr. Ria explains how advancements in CT technology, protocol optimization, and evidence-based imaging guidelines have significantly reduced radiation dose over time. Yet public perception and even some clinical decision-making still reflect outdated assumptions about risk. He argues that imaging professionals must communicate risk more clearly and contextualize radiation within the broader clinical picture.The discussion also explores the responsibility of medical physicists, radiologists, and technologists in balancing image quality with dose, ensuring protocols are clinically appropriate, and aligning imaging decisions with patient-centered outcomes. Rather than asking, “How low can we go?” the better question may be, “Is this exam delivering the right information at the right time for this patient?”Ultimately, this episode reframes CT safety as a multidimensional challenge — one that requires leadership, education, and collaboration across the healthcare system to ensure patients receive the diagnostic clarity they need without unnecessary compromise.What You’ll Learn:What “total risk” means in the context of CT imagingWhy clinical risk can outweigh radiation risk in many scenariosHow fear-based imaging decisions may unintentionally harm patientsThe evolution of CT dose optimization over timeWhy image quality and diagnostic confidence must remain centralThe role of medical physicists in balancing safety and clinical valueHow better risk communication improves patient trust and care decisionChapters:[00:00] Rethinking Risk in CT Imaging[03:12] Defining Total Risk vs. Radiation Risk[07:45] The Consequences of Avoiding Necessary Imaging[12:18] Advances in CT Dose Optimization[17:26] Communicating Risk to Patients and Clinicians[22:40] Balancing Image Quality and Safety[28:05] Leadership Responsibility in Imaging Risk[33:10] The Future of Risk-Based Imaging DecisionsFrame by Frame: Rethink Imaging Podcast is handcrafted by our friends over at: fame.so

When COVID-19 began flooding hospitals, neuroradiologists started seeing something alarming.Dr. Claudia Kirsch recalls reading cases involving venous infarcts, massive inflammation, and devastating brain injury. Patients were experiencing hemorrhages and large infarctions linked to the virus. It was a wake-up cal, one that drove her to investigate how SARS-CoV-2 was affecting the brain at a structural and biological level.One of the earliest mysteries? Smell loss.Patients were losing their sense of smell without sinus inflammation. The virus requires ACE2 receptors to enter cells, yet those receptors are limited in the olfactory bulb. So how was it reaching the brain?Emerging hypotheses point toward alternative pathways, including vascular spread and lesser-known neural structures such as the nervus terminalis, tiny unmyelinated fibers that connect the olfactory region to the hypothalamus and are associated with nitric oxide signaling, immune response, and blood supply regulation.These discoveries extend beyond COVID.The episode also explores how viruses influence inflammation more broadly including their role in cancer biology and immune modulation. Imaging is becoming central to identifying early inflammatory changes, mapping neural pathways, and understanding long-term consequences.At its core, this conversation emphasizes a powerful truth: when clinicians understand what to look for, imaging becomes predictive not just diagnostic.What You’ll Learn:What neuroradiologists saw in early COVID brain scansHow COVID may trigger vascular injury and inflammation in the brainWhy smell loss remains biologically complexThe significance of the nervus terminalis in viral spread and immune responseHow viral inflammation may intersect with cancer biologyWhy advanced imaging is essential to precision medicineChapters:[00:00] Introduction to Viral Neuroimaging[04:47] The Wake-Up Call: Early COVID Brain Cases[08:20] The Science Behind Smell Loss[14:54] The Nervus Terminalis Discovery[21:30] Neuroinflammation and Vascular Pathways[29:45] Viral Mechanisms and Cancer Risk[37:10] The Future of Imaging in Precision MedicineFrame by Frame: Rethink Imaging Podcast is handcrafted by our friends over at: fame.so
