A Prospective Pilot Study for the Evaluation of 18F- Fluciclovine PET/MRI in Radio-recurrent Prostate Cancer (RRPC-PET/MRI Study)

A Prospective Pilot Study for the Evaluation of 18F- Fluciclovine PET/MRI in Radio-recurrent Prostate Cancer (RRPC-PET/MRI Study)

To perform both PET scans and MRIs in the same setting using a simultaneous PET/MRI scanner.

Primary Objective:

--To compare the diagnostic performance of 18F- Fluciclovine pelvic PET/MRI to that of pelvic mpMRI and to determine whether 18F- Fluciclovine pelvic PET/MRI is more accurate than a pelvic mpMRI in detecting pelvic RRPC in men with biochemical recurrence with histopathology as reference standard.

Secondary Objective:

--To study inter-reader reliability of 18F- Fluciclovine pelvic PET/MRI and pelvic mpMRI among the readers.

Exploratory Objective:

--To study correlation between SUVmax and ADCmean in the pelvic RRPC.

Inclusion Criteria:

1. Male patients who are 18 years and older
2. Histologically or cytologically proven prostate carcinoma s/p definitive radiation
3. Patients suspected to have BCR based on phoenix criteria (prostate specific antigen value (PSA) of 2 ng/mL above the PSA nadir)
4. Ability to understand and willingness to sign informed consent

Exclusion Criteria:

1. Patients with any medical condition or circumstance that the investigator believes may compromise the data collected or lead to a failure to fulfil the study requirements.
2. Patients with contraindication to undergo MRI
3. Patients with prior allergy to MRI contrast agent.
4. Extreme Claustrophobia
