Study of PSMA PET/MR Guided Stereotactic Body Radiation Therapy With Simultaneous Integrated Boost (SBRT-SIB) for High-Intermediate and High Risk Prostate Cancer

"Patients enrolling on the protocol will undergo prostate-specific membrane antigen (PSMA) Positron Emission Tomography (PET)/Magnetic Resonance(MR) prior to start of the radiation treatment planning process. PSMA tracer is administered by IV injection and PET images are acquired.~Any patients found to have possible metastatic disease will undergo a standard of care confirmatory biopsy (if feasible) and receive treatment appropriate for their stage.~The PSMA PET/MR scan will be performed prior to initiation of androgen deprivation therapy (ADT)."

Patients will receive standard of care radiation therapy (SBRT)
