Rethink Imaging

Dr. Claudia Kirsch joins Rethink Imaging to discuss how viruses like SARS-CoV-2 reshape the brain through inflammation, vascular injury, and immune pathways.
From unexplained smell loss to the discovery of the nervus terminalis as a potential viral pathway, this episode highlights how advanced imaging is uncovering new insights into neuroinflammation and viral-driven disease including implications for cancer biology and long-term brain health.

Medical imaging faces a workforce crisis that cannot be solved with short-term staffing fixes.
In this episode of Rethink Imaging, Chris St. John speaks with Geoffrey Roche, SVP of Healthcare at RizePoint, about why imaging remains a hidden profession, why more than 20,000 students sit on waiting lists every year, and how outdated accreditation models are limiting access to care.
Geoffrey shares a systems-level view of workforce development, drawing from his experience across hospital systems, higher education, Siemens Healthineers, and global health education. The conversation explores apprenticeships, imaging assistants, retention challenges, and why imaging must evolve its training pathways if it wants a sustainable future.

James leads one of the region’s most advanced nuclear theranostics programs, using molecular imaging not only to diagnose cancer, but to guide and deliver treatment. This conversation stays grounded in practice: how patients are selected, how imaging drives decisions, and how programs actually get built.
In this episode of Rethink Imaging, Chris St. John sits down with Dr. James Cassuto to unpack what theranostics looks like when it’s done right, inside a real health system, serving real patients.

In this episode of Rethink Imaging, Chris St. John sits down with Dr. Ali Tejani, a neuroradiology fellow at UCSF and a national leader in radiology education, imaging informatics, and AI literacy.
Ali shares why radiology training programs must evolve now to prepare trainees for a future where AI is embedded in everyday clinical workflows.
From launching an imaging informatics and business intelligence track during residency to co-directing national informatics education initiatives, Ali explains how radiologists learn best, why traditional didactics are no longer enough, and how podcasts, social media, and hands-on AI experiences are reshaping education.
The conversation explores generational learning differences, the risk of deskilling, ethical AI use, and why being a critical, informed AI user matters more than knowing how to code.

In this episode of Frame by Frame: Rethink Imaging, host Chris St. John sits down with Jason Schneck, CEO of One Physics, to unpack how medical physics is evolving as care shifts beyond hospital walls. Jason shares a frontline view of how outpatient expansion, workforce shortages, regulatory complexity, and emerging technologies like molecular imaging and theranostics are reshaping the role of medical physicists.
He explains why the profession remains underrecognized, how consolidation and outsourcing are not threats but structural responses to modern care delivery, and why flexibility, scale, and advocacy are becoming essential to patient safety and quality imaging.
