Description:

The purpose of this study is to evaluate the diagnostic value of 18F-FDG PET/CT dynamic imaging in metastasis of non-small cell lung cancer (NSCLC). The investigators will collect dynamic 18F-FDG PET/CT scan and correlate the imaging findings with genomics and histopathological features of biopsy of primary or / and metastatic lesions in patients with newly diagnosed non-small cell lung cancer (NSCLC). At the same time, the investigators will evaluate the diagnostic value of 18F-FDG PET/CT dynamic imaging in differentiating multiple primary lung cancer from intrapulmonary metastases.
