Study Groups

68Ga-DOTATATE Injection

Group Type: EXPERIMENTAL

68Ga-DOTATATE Injection

Intervention Type: DRUG

The eligible subjects who participate in 68Ga study will be intravenously injected with 68Ga-DOTATATE Injection on Day1，and undergo PET/CT examination within 60 minutes after injection. Corresponding safety examination is performed before administration of 68Ga-DOTATATE Injection, 3h±1.0h after administration, and Day2. Telephone safety visit is conducted at Day7 after administration.

① Biochemical and tumor biomarkers results of blood or urine suggest that the subject is suspected of suffering from NETs (chromogranin A,neurospecific enolase,vasoactive intestinal peptide, serotonin (urinary 5-HIAA), gastrin, somatostatin,catecholamines,calcitonin,fasting insulin,C-Peptides(proinsulin) orglucagon abnormal biochemical indicators related to neuroen docrine tumors);

3. Unable to complete the imaging examination specified in the plan due to claustrophobia,radiation phobia or personal wishes;

4. With a history of concurrent active infection or severe heart disease;

5. Those who have used long-acting somatostatin analogs within 28 days or short-acting somatostatin analogs within 2 days before the scheduled PET/CT examination of 68Ga-DOTATATE injection;

6. Those who receive long-term and repeated treatment with high-dose glucocorticoids;

7. Pregnant or lactating women,or those who do not agree to take effective contraceptive measures from the date of signing the informed consent form to 3 months after administration;
