    The study developed CT-based models to predict malignancy in part-solid pulmonary nodules (PSNs) using vascular analysis.

  • 2

    Malignant PSNs were linked to older age, female predominance, and specific CT features like irregular shape and spiculation.

  • 3

    Vascular patterns IV (interruption) and V (distortion) were significantly more common in malignant nodules compared to benign ones.

  • 4

    Model 2, which included qualitative vascular types IV and V, showed superior predictive performance compared to other models.

  • 5

    Integrating vascular features into CT assessments enhances diagnostic accuracy and aids in preoperative risk stratification of PSNs.
