The investigators developed 18F-MPG as a targeted molecular imaging agent for noninvasive and repeatable detecting EGFR-activating mutational status. And use 18F-MPG to monitor EGFR-TKIs and chemotherapy treatment efficiency.
The goal of investigators were to evaluate the use of 18F-MPG as a novel PET/CT radiotracer to monitor EGFR-activating mutational status and identify EGFR-TKIs benefit NSCLC patients. the investigators want to evaluated the use of 18F-MPG in lung cancer imaging in adult NSCLC patients with different EGFR mutational status of primary and metastatic cancers. And the investigators want to evaluated the use of 18F-MPG in adult NSCLC patients with EGFR mutational status received non-treatment, EGFR-TKIs and chemotherapy.

tumor SUVmax value of 18F-MPG PET/CT Imaging
To quantify the accumulation, 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.
