18F-TSPF PET/CT: Each subject receives interval imaging of 18F-TSPF PET/CT and 18F-FDG PET/CT, and further follow-up.
Study summary
The investigators developed a 18F labeled small molecule, 18F-TSPF, based on c-Met TKI, as a targeted molecular imaging agent for noninvasive and repeatable detecting c-Met activation status.

Primary outcome measure(s)
Standardized Uptake Values — 1 hour To quantify the PET, a volume of interest using a 3-D sphere, was placed over the primary lung tumor, lymph nodes and distant metastases avoiding necrosis, blood vessels and normal lung tissue as much as possible on a workstation (Advantage Workstation 4.6; GE Healthcare). The maximum standard uptake value (SUVmax) normalized to body weight (kBq/mL) was calculated within the region of interest. SUVmax of primary lesion and metastatic lesion in subjects with NSCLC are measured and used to analyze correlatation with pathology or gene detection.
