Validation of FACBC for Detection of Metastasis Among High-risk Prostate Cancer Patients With Presumed Localized Disease

"Participants will fast for 4 hours to normalize their neutral amino acid levels. One hour prior to the scan, participants will drink up to 450ml of standard oral contrast. Participants will lie on the scanning bed while the bed moves through the PET/CT scanner for the CT portion of the exam. After completion of the CT scan, approximately 10 units of FACBC will be injected for the PET scan portion of the exam. The bed will move through the scanner again and the PET portion of the exam will take 30 minutes. The entire visit will take about two hours.~Standard of care procedures include conventional imaging (CT and/or MRI; bone scan and/or NaF PET per institutional standards) and radical prostatectomy with extended pelvic lymph node dissection."
