Risk stratification of prostate cancer with MRI and prostate-specific antigen density-based tool for personalized decision making.

Objectives: MRI is now established for initial prostate cancer diagnosis; however, there is no standardized pathway to avoid unnecessary biopsy in low-risk patients. Our study aimed to test previously proposed MRI-focussed and risk-adapted biopsy decision models on a real-world dataset.

Methods: Single-centre retrospective study performed on 2055 biopsy naïve patients undergoing MRI.
