What 5.2 Million CT Scans Taught Us About Patient Radiation Dose | Tom Griglock & Kalpana Kanal
In this episode of Rethink Imaging, host Chris St. John sits down with Dr. Kalpana Kanal and Dr. Thomas Griglock to discuss the newly updated Diagnostic Reference Levels (DRLs) and Achievable Doses (ADs) published ten years after the benchmark 2014 study. Analyzing a massive dataset of 5.2 million CT exams from 2025, they break down the 22% reduction in national DRLs, explain why low dose isn't always good dose, and emphasize why clinical optimization and diagnostic image quality must take precedence over endless dose reduction.
