  1. The use of multiparametric magnetic resonance imaging (MRI) and the Prostate Health Index (PHI) can improve risk stratification for men with elevated prostate-specific antigen levels.
  2. Selectively avoiding MRI in men with lower PHI scores can reduce costs and unnecessary biopsies, while ensuring timely diagnosis of clinically significant prostate cancer.
  3. Risk stratification based on PHI can optimise allocation of limited MRI resources and improve the efficiency of prostate cancer screening and early detection.
