Experimental: 68Ga-DOTATATE PET/CT
Inject 68Ga-DOTATATE and then perform PET/CT scan
Intravenous injection of one dosage of 74-148 MBq (2-4 mCi) 68Ga-DOTATATE. Tracer doses of 68Ga-DOTATATE will be used to image lesions of NET PET/CT scan.
- SUVmax [ Time Frame: through study completion, an average of 3 years ]SUVmax of focal lesions are measured on 68Ga-DOTATATE PET/CT. The SUVmax higher than that of the normal liver tissue is defined as positive.
- Diagnostic value [ Time Frame: through study completion, an average of 3 years ]Diagnostic value of 68Ga-DOTATE PET/CT for NET in comparison with 18F-FDG PET/CT
- Diagnostic value in different grades/types of NET [ Time Frame: through study completion, an average of 3 years ]Diagnostic value of 68Ga-DOTATATE PET/CT in ectopic ACTH-secreting tumor, insulinoma, glucagonoma and so on.
- Overall Survival(OS) [ Time Frame: 1 year and 5 years after been diagnosed ]Analysis of OS for patients receiving 68Ga-DOTATATE PET/CT
- Progressive free survival(PFS) [ Time Frame: 1 year and 5 years after been diagnosed ]Analysis of PFS for patients receiving 68Ga-DOTATATE PET/CT
- SSTR expression/Ki67 and SUV [ Time Frame: through study completion, an average of 3 years ]Correlation between SSTR expression/Ki 67 and SUV in PET
- Risk stratification [ Time Frame: through study completion, an average of 3 years ]Analysis of risk factors and OS/PFS
