  • The Invisible Revealed: Iodine and the Birth of Clearer Medicine

    The Invisible Revealed: Iodine and the Birth of Clearer Medicine
    Jan 20 2026
    Why Radiology's most powerful tool isn't the scanner - it's the element inside it.

    In this episode, we journey through one of medicine’s most dramatic transformations: how a single element turned blurry shadows into lifesaving clarity. From Röntgen’s eerie glowing screen in 1895 to the high-stakes, trial-and-error era of early contrast experiments, we trace the desperate quest to make the invisible visible. Enter iodine — small, mighty, and scientifically elegant.

    We’re joined again by Dr Ashesh Ranchod, who brings his trademark clarity to the chemistry, physics, and sheer audacity behind iodine’s rise in imaging. Together, we unpack the early toxic formulations, the breakthrough of tri-iodinated benzene rings, the 1950s game-changer Hypaque, and the evolution toward modern non-ionic contrast that revolutionised both CT and vascular imaging.

    If you’ve ever wondered how radiology moved from murky guesses to precise, targeted diagnosis — this is the story. Bold science. Brave pioneers. And one element that changed everything.

    Paying Homage to the Pioneers.

    Step inside the story of how radiology taught the world to see the unseen.
    Host Dr. Mantha Makume chats with Dr. Ashesh Ranchod, one of South Africa’s leading radiologists, to trace the fascinating evolution of medical imaging — from Wilhelm Röntgen’s mysterious “X-rays” to modern AI-powered scans. This episode explores the science, the pioneers, and the daring discoveries that revolutionised how we diagnose and treat disease.
