AI Software Cuts Unnecessary Prostate Biopsies by 18.9% for PI-RADS 3 Lesions on MRI

AI software reclassified PI-RADS 3 prostate MRI lesions with 98.4% sensitivity, yielding an 18.9% reduction in unnecessary biopsies. Lesion-level sensitivity was lower (78.8% vs 88.8% for PI-RADS), supporting its role as a decision aid for radiologists.

• The AI upgraded 93.1% of csPCa-positive lesions originally classified as PI-RADS 3, while deeming 24.1% of PI-RADS 3 lesions low risk.
• Sensitivity was 98.4% for overall biopsy triage but 78.8% at the lesion level, underscoring the need for combined radiologist-AI interpretation.
• The three-point risk scale from the AI provides additional triage information beyond PI-RADS, potentially reducing biopsy uncertainty.
