NETs
Conditions
Brief summary
Evaluate the diagnostic efficacy, pharmacokinetics and safety of 68Ga-DOTATATE injection PET/CT in NETs
Interventions
DRUG68Ga-DOTATATE Injection
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.

Those who have a history of neuroendocrine tumors,but require PET/CT examination for structure, location and function evaluation and disease management, and have measurable lesions; CT, MRI, 18F-FDG PET/CT or other imaging examinations are suspected of being NETs or those with space-occupying lesions and at least one of the following: 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); ②Multiple endocrine neoplasia type 1 (MEN1) and Lindau syndrome (VHL) with familial tendency to be susceptible to NETs (symptomatic and/or asymptomatic cases; with biochemical or anatomical imaging evidence of the disease); 5. The subjects or their guardians fully understand the content,process and possible risks of the trial and voluntarily sign the informed consent form.
Exclusion criteria

Unable to remain relatively still during the imaging examination (such as coughing, severe arthritis, etc.), or body shape and/or weight exceeds the applicable range of the examination equipment; 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.
