In this episode of Radiology with a Dose of Insight, we explore one of the most nuanced and often debated areas in modern imaging: the use of contrast agents in patients at risk of kidney injury.

Joined by Dr Ashesh Ranchod and Dr Muhammed Hassen, we unpack the evolving relationship between radiologists and nephrologists — from historical caution and “contrast hysteria” to a more collaborative, evidence-based approach.

Through real-world scenarios, including high-stakes emergency decisions, we examine the balance between diagnostic urgency and renal safety. The conversation dives into the shift from Contrast-Induced Nephropathy (CIN) to Post-Contrast Acute Kidney Injury (PC-AKI), the true mechanisms of kidney injury, and how often contrast is wrongly blamed.

We also tackle the clinical “gray zone” — patients with borderline renal function — where decision-making becomes less about guidelines and more about judgment, communication, and shared responsibility.

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. ]]> Health & Fitness Tue, 20 Jan 2026 07:00:00 +0200 0 0 The Invisible Revealed: Iodine and the Birth of Clearer Medicine 0 0 Solid Gold Podcasts #BeHeard full 29:22 Radiology with a Dose of Insight https://iono.fm/e/1610591 https://iono.fm/e/1610591
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. ]]> Health & Fitness Thu, 23 Oct 2025 10:30:00 +0200 0 0 125 Years of Radiology 0 0 Solid Gold Podcasts #BeHeard full 25:31 Radiology with a Dose of Insight
