Conditions
Summary
The goal of this clinical trial is to evaluate an investigational ultralow dose positron emission tomography (PET) imaging technique for neuroendocrine tumor detection and monitoring. The main question it aims to answer is: Can the investigators optimize the timing, scan duration, and image reconstruction to reduce the radiation dose 10-100 fold of the current clinical standard? Participants will be injected with a radioactive tracer that binds to a tumor specific protein called somatostatin receptor 2 (SSTR2) and be imaged on a new type of high sensitivity PET scanner for up to 3 hours
Eligibility
Inclusion Criteria3

- Medication \& Prior Treatment Exclusions: SSTR targeted therapies
- Pregnant or breastfeeding individuals (negative pregnancy test required)
- Inability to provide informed consent
- Any condition that, in the investigator's judgment, may compromise participant safety or study integrity.
