Patients diagnosed with lung adenocarcinoma
Conditions
Interventions
Gold Standard:All patients underwent thoracoscopic or open thoracotomy surgery within two weeks of the examination at our hospital to obtain pathological results. Two senior pathologists examined the
Index test:PET multimodal metabolic parameters (SUVmax, SUVmin, SUVmean, SUVpeak, MTV, TLG)

Inclusion criteria
Inclusion criteria: 1. The CT image of the lesion shows a single pulmonary lesion with a maximum diameter of <=5 cm; 2. Both lung fields are clearly distinguishable, with no other chest diseases or lymph node abnormalities. 3.

Exclusion criteria
Exclusion criteria: 1. Patients who cannot obtain pathological results; 2. Patients with poor respiratory cooperation and blurred images; 3. A history of any other malignant tumors within the past 5 years; 4. Known to be allergic to the injection or its excipients; 5.
