Frame by Frame: Rethink ImagingCould Our Obsession with Dose Be Risking Lives?In this illuminating episode of Frame by Frame, host Chris St John continues his in-depth conversation with Dr. Ehsan Samei to explore how we define and measure quality in medical imaging. Dr. Samei emphasizes that radiation dose, while important, tells only part of the story. Instead, quality should be viewed through a multi-dimensional lens that includes task-based performance, image clarity, contrast, and diagnostic relevance.Drawing on examples like breast and lung cancer screening, Dr. Samei shows how imaging can improve outcomes when guided by validated metrics and clinical collaboration. He also highlights the challenges of creating standardized measurements...2025-04-1737 min
Frame by Frame: Rethink Imaging'The Real Harm Is in Missing the Diagnosis' with Dr. Ehsan SameiIn this episode of Frame by Frame, host Chris St John is joined by Dr. Ehsan Samei, a leading medical physicist and advocate for patient-centered imaging.Dr. Samei challenges long-held assumptions about radiation risk, urging a shift away from fear-based thinking. He critiques the limitations of population-based radiation thresholds and emphasizes why shared decision-making should drive medical imaging practices.Through accessible examples, Dr. Samei explains why delayed or denied imaging can often pose a greater risk than the radiation itself. He also breaks down the widely debated Linear No-Threshold model and how it’s frequently misunderstood in...2025-04-0338 min
