Inclusion criteria

Inclusion criteria: 1. Aged 18-79 years old; 2. Thin-Section CT shows multiple lung nodules, which are planned to be treated with lobectomy/segmentectomy; 3. Thin-Section CT scan: the largest diameter of the lung window of the main lesion: d 0 to 20mm, diagnosed as clinical stage I (cT1N0) (UICC-TNM 8th edition); 4. ECOG score 0-1; 5.
