External Validation of <scp>MRI</scp> ‐Based Prostate Cancer Risk Calculators in an Australian Cohort

Use of prostate biopsy decision-making tools provides avenues for individualized health care based on patient-specific risk factors. This study has successfully completed external validation of nine risk calculators, with one demonstrating adequate discriminatory capacity in all patients and three in biopsy-naïve patients. Systemic use may have a 12% net clinical benefit amongst biopsy-naïve patients, thereby reducing healthcare system burden.
