68Ga-RM2 PET/MRI in Biochemically Recurrent Prostate Cancer

This phase II/III trial studies how well gallium (Ga) 68-labeled gastrin-releasing peptide receptor (GRPR) antagonist BAY86-7548 (68Ga-RM2) positron emission tomography (PET)/magnetic resonance imaging (MRI) works in detecting prostate cancer in patients with negative computed tomography (CT) scan and elevated prostate-specific antigen levels after treatment with surgery or radiation. PET/MRI scans take both PET and MRI images at the same time and combine them into a single picture and is used to describe information regarding the function, as well as location and size of a tumor. 68Ga-RM2, a compound made of a radioactive agent linked to a pharmacological substance that is strongly attracted by a substance made by tumor cells, to detect prostate cancer. 68Ga-RM2 PET/MRI may be able to see smaller tumors than the standard of care contrast-enhanced CT or MRI scan
