Methods: NSCLC patients were examined by PETCT, and the performance and accuracy of PETCT in the diagnosis of mediastinal lymph node metastasis were analyzed. Results: PETCT can show the location of tumor activity in NSCLC patients, including the location of lymph node metastasis and extrapulmonary metastasis, with higher accuracy than CT and MRI examinations. Conclusion: PETCT has important application value in the diagnosis of NSCLC.【Keywords】PETCT; NSCLC; mediastinal lymph node metastasis; diagnosis
