About The Study: Given increasing rates of coronary artery disease (CAD) worldwide, the findings of this study of marked variation in radiation dose to patients from diagnostic testing identify a critical need for training, standardized protocols, and updated equipment to reduce radiation worldwide. This especially affects patients in low- and middle-income countries and patients undergoing coronary computed tomography angiograph. There are therefore important opportunities to improve the quality of CAD diagnosis for patients across the globe.
