    Forty-four percent of patients undergoing coronary computed tomography angiography exceeded the 9 millisievert radiation guideline.

  • 2

    The study evaluated radiation exposure in 19,302 patients across 742 centers in 101 countries during noninvasive coronary imaging.

  • 3

    Median radiation doses varied significantly by imaging modality, with CCTA showing the highest variability among centers.

  • 4

    Geographic and economic factors influenced radiation exposure, with lower doses in Western Europe and higher doses in Latin America and Africa.

  • 5

    The findings indicate a need for improved training, standardized protocols, and updated equipment to enhance safety in cardiac imaging.
