JAMA February 2026 Worldwide Radiation Dose in Coronary Artery Disease Diagnostic Imaging

This global study examines the ionizing radiation exposure that patients experience during common medical imaging procedures used to diagnose heart disease. By analyzing data from over 100 countries, the researchers discovered significant disparities in dosage depending on the specific type of technology used and the geographic location of the patient. A major finding is that individuals in low-income regions are often exposed to much higher levels of radiation than those in wealthier nations, particularly during coronary CT scans. Ultimately, the text highlights a pressing need for standardized protocols and modern equipment to ensure that diagnostic testing is safer and more equitable for patients worldwide.
