    Abdomen CT examinations show significant radiation dose variation, with a six-fold range across 1033 protocols, increasing cancer risk for patients.

  • 2

    Local clinician decisions significantly influence radiation dose variation, rather than patient factors or machine characteristics.

  • 3

    Standardization of radiation doses is essential, yet developing protocols is resource-intensive and lacks a consensus-based approach.

  • 4

    A crowd-sourcing method was employed to identify optimized abdomen CT protocols from a large international radiation dose registry.

  • 5

    Size-adjusted radiation doses were calculated to minimize patient size impact, allowing for better comparison of facilities.
