Why Gonadal Shielding in X-rays Actually Increases Radiation Dose

Frame by Frame: Rethink Imaging

In this episode of Frame by Frame: Rethink Imaging, host Chris St. John is joined by Dr. Summer Kaplan, Associate Professor of Clinical Radiology at the University of Pennsylvania and pediatric radiologist at Children’s Hospital of Philadelphia, to examine a major shift in radiation safety protocols—why gonadal shielding is being reconsidered in modern radiology.

Dr. Kaplan discusses the findings of groundbreaking research showing how traditional shielding can actually increase patient radiation exposure due to interactions with automatic exposure controls in advanced imaging systems. Together, they explore how modern equipment, data-driven protocols, and AI have revolutionized imaging safety, and what this means for radiology professionals and patients alike.

This episode is a must-listen for anyone working in diagnostic imaging, medical physics, or patient safety, offering a forward-thinking perspective on how to communicate, implement, and trust in evolving best practices in radiation protection.

What You’ll Learn:

• Why gonadal shielding may increase radiation exposure with today’s imaging systems
• How automatic exposure controls respond to shielding—and the unintended consequences
• The science behind moving away from routine gonadal protection in X-rays
• How to educate patients and families about updated radiation safety protocols
• The role of organ sensitivity in radiation risk assessment
• Advances in imaging technology and AI that reduce exposure without the need for shielding
• Why pediatric imaging requires unique safety considerations
• How professional guidelines and institutional policies are changing nationwide
