    CTPA is the gold standard for diagnosing pulmonary embolism, with high sensitivity and specificity.

  • 2

    Reducing iodinated contrast media dosage minimizes risks of contrast-induced acute kidney injury and ecological impact.

  • 3

    Photon-counting detector CTs (PCD-CTs) enhance image quality and contrast, allowing for reduced contrast media use.

  • 4

    This study compares PCD-CT and energy-integrating detector CT (EID-CT) for optimizing contrast media protocols.

  • 5

    Results indicate that PCD-CT can maintain diagnostic image quality while using lower contrast media doses.
