Eligibility
Inclusion criteria
Inclusion criteria: Inclusion criteria: a. Excellent thin-slice CT image quality during plain scan (slice thickness = 2cm nodules shall not be less than 20% of the total number of cases. (2) Accurate diagnosis of lung adenocarcinoma subtypes: a. Postoperative pathological staging is T1N0M0; b. Preoperative CT of the chest showed ground-glass nodules (pure ground-glass nodules and mixed ground-glass nodules) (note: Lung adenocarcinomas with solid nodules, mostly IAC, are not included in the study); c. Preoperative chest CT showed that the maximum cross-sectional average diameter of the nodules was 1cm, but = 2cm nodules shall not be less than 30 %); c. The distance from the pleura is = 2cm nodules not less than 50% of the total number of cases. (5) Assess mediastinal and hilar lymph node metastasis: Underwent radical resection of lung cancer and lymph node dissection, pathology confirmed whether mediastinal and hilar lymph node metastasis. (6) Assessment of extrathoracic metastasis: After undergoing radical resection of lung cancer and lymph node dissection, surgery or puncture pathology will determine whether there is extrathoracic metastasis.
Exclusion criteria
Exclusion criteria: a. Obvious imaging artifacts; b. Respiratory motion artifacts; c. Low-dose CT images (single dose less than 1.5 mSv); d. Patients received radiotherapy and chemotherapy before surgery.
