Characterization of 18F-Fluciclovine PET Amino Acid Radiotracer in Resected Brain Metastasis

Summary

This study is for patients who have had surgery to remove brain metastasis and are planned to have stereotactic radiosurgery (SRS) after their brain surgery. It will be optional for patients to have a pre-surgery 18F-Fluciclovine PET/CT scan. The goal of the study is to determine whether a specific imaging agent, known as 18F-Fluciclovine, will help physicians evaluate the extent of surgery and determine if there is any visible tumor above what MRI alone can identify as well as improve the physicians' ability to detect recurring disease. This agent (18F-Fluciclovine) is investigational for the imaging of brain metastases.

Interventions

• Drug
  18F-Fluciclovine

  Patients will receive 5-mCi dose (+/- 20%) of 18F-Fluciclovine intravenously as a bolus injection. They will be required to fast for at least four hours prior to 18F-Fluciclovine injection. Patients will be positioned for PET/CT brain imaging and will be injected with 18F-Fluciclovine immediately prior to PET data acquisition. PET data will be collected in list mode up to 25 minutes post-injection. PET images will be reconstructed in two ways: as a standard static image of data acquired between 10 to 20 minutes post-injection, and as a dynamic series of four 5-minute frames between 5 to 25 minutes post-injection to allow for motion assessment and correction and time-dependent observations.
