Positron Emission Tomography / Magnetic Resonance Imaging (PET/MRI) Guided Biopsy in Men With Elevated PSA

Summary

In 22% of patients with elevated Prostate-specific antigen (PSA) MRI guided biopsy will not detect significant prostate cancer (PCA) (defined as either: Gleason score (GS) ≥ 3+4 or tertiary pattern 5, or final stage ≥ pT3a and/or pN1). Therefore this study evaluates the ability of \[68Ga\]PSMA PET/MRI to detect and localize significant primary PCA to accurately direct prostate needle biopsy using the Gleason score from the histology of the core biopsies as standard of truth.
