Overview

In this study, 288 patients will be randomized 1:1 to either having only the standard of care MRI prior to surgery versus having the standard of care MRI and the PSMA PET scan. PET (and MRI) findings will be validated against whole mount pathology. Pre-surgical imaging findings will also be evaluated in the context of affecting subsequent surgical plans and impacting actual patient outcomes.
