    The study investigates task-based automatic keV selection for optimizing radiation and contrast media doses in photon-counting detector CT.

  • 2

    Low X-ray tube voltage scanning enhances iodine contrast and reduces radiation exposure, crucial for maintaining image quality in CT angiography.

  • 3

    Elderly patients may benefit from reduced contrast media doses, while younger patients may require lower radiation doses to mitigate ionizing radiation risks.

  • 4

    The study evaluates four distinct CTA protocols to assess the impact of varying radiation and contrast media doses on contrast-to-noise ratio.

  • 5

    In vivo validation is essential due to the dynamic nature of contrast media distribution, which cannot be accurately replicated in phantom studies.
