    CT examinations contribute significantly to medical radiation exposure, accounting for 60% despite only representing 9% of all ionizing radiation exams.

  • 2

    Manual determination of scan lengths often leads to overscanning in 30-60% of cases, increasing unnecessary radiation doses.

  • 3

    AI has potential to optimize scan ranges in CT imaging, but its application in automatic delineation of scan ranges has been minimally explored.

  • 4

    The study developed an AI model to segment anatomical structures for scan range determination across various body regions.

  • 5

    A retrospective cohort study analyzed 154,752 CT examinations, ultimately including 1,146 patients to evaluate the AI model's performance.
