    Pulmonary embolism is a leading cause of cardiovascular morbidity and mortality, necessitating rapid and accurate diagnosis.

  • 2

    CT pulmonary angiography is the gold standard for diagnosing pulmonary embolism but requires optimal opacification of pulmonary arteries.

  • 3

    Traditional CTPA protocols use fixed trigger delays, which may not account for individual patient hemodynamics, risking image quality.

  • 4

    A patient-adaptive trigger delay algorithm has been developed to improve contrast enhancement timing in CTPA, potentially enhancing image quality.

  • 5

    This study aims to compare the efficacy of patient-adaptive protocols against traditional methods in improving CTPA image quality.
