    Chronic thromboembolic pulmonary hypertension (CTEPH) results from unresolved clots and small-vessel arteriopathy in pulmonary arteries.

  • 2

    Small-vessel arteriopathy contributes to elevated pulmonary vascular resistance and residual pulmonary hypertension after pulmonary thromboendarterectomy.

  • 3

    High-resolution photon-counting detector CT (PCD-CT) can detect subtle morphological changes in lung microcirculation in CTEPH patients.

  • 4

    The study involved 29 CTEPH patients with confirmed pulmonary hypertension and a mosaic perfusion pattern observed on chest CTA.

  • 5

    Mosaic perfusion patterns on CT highlight areas of hypo- and hyperperfusion, indicating potential small-vessel disease in CTEPH.
