18F-C-SNAT4(Stanford University)

Primary Objectives
* Determine the biodistribution of [18F]-C-SNAT4 in 5 healthy volunteers. Secondary Objectives
* Determine the dosimetry of [18F]-C-SNAT4 PET in healthy volunteers and patients with lung cancer.
* Determine the acute toxicity of [18F]-C-SNAT4 PET in healthy volunteers and patients with lung cancer.
* Determine whether uptake in [18F]-C-SNAT4 PET imaging is significantly different in tumor and corresponding contralateral noncancer tissue in patients with lung cancer (tested by Wilcoxon test) before the therapy.
* Determine/verify the safety profile of the [18F]-C-SNAT4 radiotracer, as an imaging agent in patients with lung cancer.
* Determine the time of maximal [18F]-C-SNAT4 radiotracer uptake post injection.
