Summary
Brief summary (as posted)
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

- Ultralow dose 68Ga-DOTATATE imaging group
- description
- Participants will be enrolled for an ultralow dose PET scan to evaluate image quality and optimize timing and reconstruction after reducing radiation doses 10-100 fold. Participants will be injected with a very small amount of radiotracer and imaged on a PET scanner for up to 3 hours
