Primary Outcome Measures:
  • Quantitative measurement of standardized uptake values (SUVs) of lesions. [ Time Frame: 1 year ]
    The quantitative analysis will be performed by the same person for all cases, and the standardized uptake value (SUV) of each tumor will be measured using a volume of interest (VOI) method.

Secondary Outcome Measures:
  • Number of participants with adverse events as a measure of safety after 68Ga-NEB injection and PET/CT scanning. [ Time Frame: 1 year ]

Enrollment: 31
Study Start Date: March 2014
Primary Completion Date: October 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 68Ga
In patients in suspicion of lung cancer or lung tuberculosis; in patients with differential diagnosis difficulties; without treatment or surgery. They underwent a standard routine 18F-FDG PET/CT first, and were injected 10~20MBq 68Ga-Alfatide II in the next day, followed by whole body PET/CT acquisitions.
Radiation: 68Ga-labeled peptides of dimer RGD (Alfatide II) and 18F-FDG
