Detection and localization of carcinoma within the prostate using high resolution transrectal gamma imaging (TRGI) of monoclonal antibody directed at prostate specific membrane antigen (PSMA)--proof of concept and initial imaging results.

Purpose: Molecular imaging methods may identify primary prostate cancer foci and potentially guide biopsy and optimal management approaches. In this exploratory study, safety and first human imaging experience of a novel solid state endocavity transrectal gamma-imaging (TRGI) device was evaluated.

Methods: Twelve patients received 5 ± 0.
