    Cardiac CT is increasingly used in children with congenital heart disease for diagnosis and pre-surgical planning.

  • 2

    Photon-counting detector CT (PCD CT) offers improved image quality and reduced radiation exposure compared to conventional energy-integrating detector CT.

  • 3

    A study compared PCD CT and energy-integrating detector CT in pediatric patients, focusing on image quality and radiation dose.

  • 4

    The study included 37 matched pediatric patients for both PCD CT and energy-integrating detector CT to ensure homogeneity.

  • 5

    PCD CT demonstrated a significant reduction in radiation dose while maintaining consistent imaging quality compared to energy-integrating detector CT.
