This pilot clinical trial studies how well fluorine F 18 d-FMAU (18F-FMAU) positron emission tomography (PET)/computed tomography (CT) works in diagnosing and characterizing prostate cancer. A PET/CT scan is an imaging test that uses a small amount of radioactive tracer that is given through the vein to take detailed pictures of areas inside the body where the tracer is taken up. Radiotracers such as 18F-FMAU may help to find the cancer and see how far the disease has spread.



I. To perform a prospective clinical imaging evaluation of 18F-FMAU PET/CT in addition to multiparametric magnetic resonance imaging (mpMRI) and standard transrectal ultrasound (TRUS)-guided 12-core biopsy for detection and localization of primary tumor in 40 men with suspected prostate cancer based on elevated/rising prostate specific antigen level, abnormal digital rectal exam, or those with prior negative standard biopsy who are now returning for a standard of care follow-up.

II. To examine the associations between the PET derived imaging parameters, serum PSA, mpMRI parameters (apparent diffusion coefficient [ADC], Ktrans) and the biopsy histopathology parameters.


Patients receive radiotracer F 18 d-FMAU intravenously (IV) over 1 minute and then undergo 18F-FMAU PET/CT on day 1. Patients then undergo standard of care multiparametic MRI and standard of care transrectal ultrasound-guided biopsy.

After completion of study treatment, patients are followed up at 24-96 hours.
