    Lung cancer is a leading cause of cancer deaths, with increased focus on early diagnosis and screening due to rising new lung lesions in cancer survivors.

  • 2

    Current lung nodule assessment algorithms are primarily based on cancer-naïve cohorts, lacking specific guidelines for patients with prior malignancies.

  • 3

    Morphological characteristics like spiculation and lobulation are crucial in differentiating between new primary lung cancer and metastatic disease.

  • 4

    Radiology reader variation can lead to inconsistent interpretations of pulmonary lesions, impacting clinical management and patient outcomes.

  • 5

    The AI-SONAR study aims to evaluate semantic CT imaging features to improve the stratification of malignant lung lesions in patients with a history of cancer.
