Eligibility
Inclusion criteria
Inclusion criteria: 1. Preoperative high-resolution CT performed at our hospital with a radiological diagnosis of pulmonary ground-glass nodules. 2. The maximum diameter of the nodule was less than 2 cm, and the proportion of ground-glass components (manifested as cloud-like increased density shadows with visible internal vascular and bronchial textures) on thin-slice images was more than 50%. 3. Definitive pathological diagnosis obtained via surgical resection or CT-guided needle biopsy. 4. Complete clinical, imaging, and pathological data available.
Exclusion criteria
Exclusion criteria: 1.CT imaging demonstrates a pure solid nodule, or a part-solid nodule with a solid component ratio greater than 50%; 2.CT imaging is compromised by severe respiratory motion artifacts, metal artifacts, or high noise levels, hindering the assessment of nodule characteristics; 3.Imaging studies or tissue sampling were conducted outside our institution, or patients were referred to external facilities for treatment following their initial workup at our hospital; 4.Before undergoing the current CT scan, the patient had been subjected to any therapeutic intervention for the lung nodule, such as anti-infective treatment, ablation, or surgical resection; 5.It has been confirmed by pathology or clinical follow-up that lymph node metastasis or distant metastasis is present;
