    Acute pulmonary embolism (PE) is a leading cause of cardiovascular death, while chronic thromboembolic pulmonary hypertension (CTEPH) can develop from unresolved PE.

  • 2

    CTEPH is characterized by increased mean pulmonary artery pressure and specific imaging features, but its diagnosis is often delayed due to subtle signs.

  • 3

    Dual-energy CT (DECT) allows for mapping pulmonary perfusion, helping to visualize and quantify perfusion defects in both acute PE and CTEPH.

  • 4

    Single-phase dual-layer dual-energy CT (dlDECT) has shown potential for detecting and quantifying pulmonary perfusion abnormalities in acute PE and CTEPH.

  • 5

    The study aimed to evaluate dlDECT's diagnostic ability to differentiate between acute and chronic stages of pulmonary thromboembolism.
